    If you have an LG TV, ACR tracking is ON BY DEFAULT and you need to turn it off manually. It is well hidden, in settings, "Additional Settings", "Live Plus" needs to be switched off.

    It is mind-boggling that there is no uproar over this. Of course, if the EU were to make a fuss, Americans would be all screaming "it's over-regulating!".

    • burnerthrow008 9 months ago ago

      None of the major TV manufacturers is based in the US, so I guess we won't have to worry about the EU regulating ACR, will we?

      Apropos of nothing, what other country besides the US has a law that specifically prohibits giving a bribe to a foreign government?

        The EU tries to regulate things that get too dangerous to its citizens. The important part though is enforcement which due to limited resources will inherently focus on the biggest players, where the impact is greatest. Players don't get bigger than US based big-tech. It's not unreasonable at all once you think about it.

        > what other country besides the US has a law that specifically prohibits giving a bribe to a foreign government?

        They allow and encourage lobbying which is literally used to the same effect. So it's a bit of a moot point, more like posturing than anything else... Much like some apropos :).

        You clearly dont know how regulation works, EU pushed many corporation to globally change their arrogant ways, ie apple dropping their proprietary plug, globally. Thats the power of half a billion relatively rich market.

        The other part is immature basic whataboutism that doesnt deserve a response, I am sure you can do better, and more on topic hopefully.

          Never mind about the plug; we get third party app stores!

        None of Apple, Facebook, Twitter, Microsoft, or Google are based in the EU; all have faced issues due to operating in the EU.

          I think the GP post meant that EU only wants to regulate tech if it's American.

            Not really, they're very much pissed about Chinese EVs now but the EC is tooo slooow to act. The Biden administration already hit them with tariffs and they're now considering banning the software that phones home. No need for weather baloons when you have cars with cameras and microphones all over the place.

      My strategy is I never accept the ToS on the TV. By and large major manufacturers don’t track unless the ToS are accepted after Vizio was caught. I still get firmware patches and can do home automation signals from the TV activity on LG without ever accepting the ToS. YMMV. Periodically after a firmware update it prompts to accept the ToS again otherwise it’s pretty silent. I do not however use any smart tv features. For my prior generation I just never attached them to a network.

      • jwr 9 months ago ago

        I didn't accept them either. That didn't prevent LG from auto-enabling the ACR.

        • fnordpiglet 9 months ago ago

          How did you observe that it was phoning it home? My network monitoring indicates it’s only checking firmware, but I have 2024 models.

          • jwr 9 months ago ago

            I did not watch the network transmissions, I just noticed that the setting is ON by default.

      • meowster 9 months ago ago

        I hope you never have a guest that accepts the ToS.

        • fnordpiglet 9 months ago ago

          Friends don’t let friends accept TOS.

  • moandcompany 9 months ago ago

    Aside from not having one of these devices at all, or disconnecting it from internet access, if you have one and want to opt-out of ACR (Automatic Content Recognition), you need to make sure that you did not select to 'opt-in' to "personalization" type features on the device.

    ACR opt-ins are not presented to end-users with a clear statement of what the opt-in means or what will happen with your data from your device and are often presented as turning on "personalization" (generally, for advertising purposes).

    The various TV or tv-related device manufacturers use different names for "ACR," so you'll need to decipher what your manufacturer calls this to disable the feature. Consumer Reports has a useful guide covering multiple brands on how to turn off ACR: https://www.consumerreports.org/electronics/privacy/how-to-t...

    If you find that your device has already been opted-in, you can disable the selection, and submit a request to have your device's information removed in some jurisdictions. You can also select to have your device's identifier id (e.g. "PSID" etc) reset from the device before performing a full factory/configuration reset of the device and setting it up again. If you fully reset the device, you'll want to watch out for the ways the manufacturer will try to get you to opt-in during the setup process. Many people have ACR-turned on without knowing.

    Adding a few more opt-out guides:

    https://www.tomsguide.com/how-to/stop-your-snooping-smart-tv...

    https://www.zdnet.com/home-and-office/how-to-disable-acr-and...

    It's also worth firewalling, or at least using dns-based blocking, any "smart tv" type devices on your network. Some of them even do periodic scans of your network and send that information to the manufacturer when they "phone home."

    • jwr 9 months ago ago

      On an LG TV, ACR tracking is deceptively called "Live Plus", and it is on by default. I was very careful not to opt in to anything, but they it was still on when I discovered it. Also, you apparently do not own your homescreen, it's their property to do with as they wish.

    • keraf 9 months ago ago

      I run AdGuard at my parent’s home and it’s crazy the amount of logs (blocked DNS queries) I get from the TVs alone. Before that Windows was the biggest offender but I switched them to Linux Mint since.

      • Groxx 9 months ago ago

        Mint has been by far the most stable / least "requires CLI fix on a weekly basis" distro I've used so far, but I gotta ask: how's that working out?

        I like it a fair bit, but I've still had to figure out weirdly broken things like "captive portals always look like the wifi didn't connect at all, but `nmcli c up` fixes that" which I can't imagine most non-computer-oriented-Windows-haters in my life would be able to manage...

        • keraf 9 months ago ago

          Honestly, for my parents it has been a delightful experience. They have quite a basic usage of their computer, mainly web browsing, some Excel/Word, managing files like photos, and occasionally printing.

          I didn't brief them much, I just installed and configured everything that was necessary for them, and let them figure out the rest. To my surprise, they managed everything on their own! Which made me realize how far UX went in the Linux world.

          In terms of maintenance, every six months when I get home for a visit, I run some updates and answer some of their questions. It's very low maintenance, especially compared to Windows.

          Also, I noticed quite an interesting side effect when installing Mint for non-techy people. They feel empowered because I trust them to run Linux, which they believe is reserved to the elite techies. This also makes them respect their computer more, which in turn makes them run into less issues as they are more careful with that they do.

        How long until these companies start hardcoding dns providers?

    • LegitShady 9 months ago ago

      I was looking at getting a TV and they all have garbage "smart" features I don't want. Someone told me to get a sceptre tv without any of that but I can't find them in my country and their actual panels don't seem that great.

      So all thats left is looking for commercial panels but a lot of those have built in content management systems now too.

      • ipython 9 months ago ago

        Why not take advantage of the subsidized price of the “smart” model, never plug it into the internet or connect it to wifi, and just plug in your devices of choice? Best of both worlds.

        • schlipity 9 months ago ago

          I think the only real problem with that is at some point (if they aren't already) they will embed cellular modems and just exfiltrate the data that way. They do this now in cars, why not TVs too?

          • m463 9 months ago ago

            I worry that this is what 5g is designed for. Look up 5g mmtc.

              Easy. You mess up the antenna or put a big lump of metal on it.

              • m463 9 months ago ago

                Very hard to do in practice.

        • bitwize 9 months ago ago

          1) From the perspective of the manufacturers that's theft of service. The manufacturers will implement measures to ensure your use of the TV is contingent upon them continuing data collecting and serving ads. Think TVs piggybacking off any available wireless connection (even LTE or 5G), or simply refusing to function until the network is set up.

          2) That's still a lot of potentially crash-prone crud that's running. Better to just buy a Sceptre or maybe a large computer monitor, and have nothing running that isn't dedicated to "get pixels into eyeballs".

          • advael 9 months ago ago

            If this model of "theft of service" is legally enforceable, then significant swaths of this industry are engaging in false advertising and possibly full-on fraud by not making this agreement they're entering into clear to customers prior to their purchase of the device

            From an ethical perspective, you will never convince me to feel bad about any "theft" of this kind, and this kind of dilution of concepts like "theft" and "crime" is likely responsible for the emotional valence of those terms reading a lot less significantly negative to people

            • bitwize 9 months ago ago

              I'm not saying that you should feel bad about it. What I am saying is that the manufacturers won't feel bad about fighting you on this issue, and coming up with ways to force you to see the advertisements they want you to see, and turn over the data they want on you.

              It's a principle I'll call Kellner's Law: If a company makes a product or service available free or at a discount by involving advertisers, from the company's perspective that creates an implicit contractual obligation on the customer's part to see the ads; and any attempt to take advantage of the freebie/discount whilst avoiding the ads will be considered a form of theft, legitimizing any technical or legal means at the company's disposal to force customers to see the ads, or else to withdraw service from those who try to avoid them. Kellner's Law explains a lot of corporate behaviors in this space, including crackdowns by YouTube and other sites on Web-based ad blockers.

              I named it for Jamie Kellner, a television executive who when TiVo (which famously allowed skipping ads in television programs recorded to the device) came out, said "Your contract with the network when you get the show is you're going to watch the spots" and that skipping ads with a device like TiVo was "actually stealing programming".

              • advael 9 months ago ago

                Kellner's law. I like it. It's an excellent illustration of the cowardice and hostility toward customers that comes from being in the subscription-twiddling business model

                If Kellner wanted to make a deal with cable subscribers, why didn't he advertise cable that way? "If you buy our package and agree to watch ads when they come on in order to support our monetization model, you can watch over a hundred channels!"

                But he didn't do that, of course. Instead, when his business model clashed with reality, he blamed the customers for violating an imaginary contract they never signed. Just because execs want to imagine violations of their assumptions as crimes doesn't mean that they actually are, and we should be using every meager lever of power we have access to to prevent governments from making laws to appease people like him, because every time a law like that is made, more people's rights are made subject to the arbitrary retroactive demands of delusional businessmen

            I opened mine up and soldered the wifi antenna leads together, should stop that problem :)

            • meowster 9 months ago ago

              Unfortunately 99.998% of the population can't do that. I'm glad you found a solution for yourself, but that doesn't help everyone else, so everyone else will reward the manufacturers by buying them and leaving them able to phone home, so manufacturers will just push the boundaries a little further next time and that might impact you in a way you can't easily mitigate.

              • nikisweeting 9 months ago ago

                Obviously, but I also vote for right to repair laws and "reward" the right manufacturers by telling my family to buy devices that are easier to hack/repair.

          • yesssql 9 months ago ago

            What? I don't buy things based on ads, it's all fast food and cheap slop. Does that mean I stole my TV?

    • djhworld 9 months ago ago

      Just taken a look at my Adguard Home query log for my TV, it seems to try and make hundreds of requests to "logs.netflix.com" for some reason - I'm not a subscriber to Netflix, I've never opened the Netflix app, I just turned on the TV and it's sitting on a HDMI source that's turned off so it isn't even doing anything

      ...and yet it keeps trying to connect to "logs.netflix.com" for reasons I do not understand. Granted, it could be just crappy retry logic, but still, why ping this endpoint when I'm not even using netflix!

  • bschwindHN 9 months ago ago

    So much engineering effort wasted with zero benefit to society.

    • mway 9 months ago ago

      Unfortunately, benefit to society seems to very rarely be the goal anymore.

      Cynically, as time goes on, it feels more and more as though we exist to be maximally extracted from, rather than to enjoy any intended benefit (where the benefit is not a happy byproduct that exists only because it is massively subsidized by aforementioned extraction).

      • gary_0 9 months ago ago

        > Unfortunately, benefit to society seems to very rarely be the goal anymore.

        If it ever was. Most of these businesses are still owned by the same people--the Sam Altmans, the Brins and Pages, the Elon Musks, the Steve Huffmans--who started out with the "not in it for the money" and "do no evil" rhetoric, and now their actions show that all that was just a lie from the start.

        • OrigamiPastrami 9 months ago ago

          Call me naïve, but I actually suspect Brin started out believing in "do no evil" and changed over time after becoming ridiculously wealthy. Having the misfortune of actually knowing some of the other people though, I firmly believe they were shitty from the beginning.

          • gary_0 9 months ago ago

            Not living up to your word because you lack the moral fortitude, rather than having ill intent from the beginning, is still lying. You said you would do something, then ended up doing effectively the opposite. "I didn't lie, circumstances changed" is a bullshit cop-out, especially when it's a billionaire saying it.

            • cgriswald 9 months ago ago

              Lying requires the speaker to know that what he is saying is false. That’s what the word means.

              By all means castigate Brin all you like but if you want to show he lied in this instance you have to show it was always a lie.

                Is a doctor allowed to abandon their Hippocratic oath because they aged 15 years?

                • cgriswald 9 months ago ago

                  If he does, did he lie when he swore the oath?

                  • Eisenstein 9 months ago ago

                    If he lied when he swore the oath, is he still a doctor?

                    BTW, I like this game: 'endlessly avoid making a point'. The winner is the person who gets the other one to end up questioning something that is required for a shared reality -- thus effectively admitting they might as well be arguing with themselves.

                    • cgriswald 9 months ago ago

                      In my opinion your question is unanswerable because if he lied when he swore the oath he was never a doctor.

                      Can you explain how your question connects to the rest of thread? I can explain the thread if you don’t understand it, as you admit.

                      • Eisenstein 9 months ago ago

                        Please do explain because if you are trying to make a point it is escaping me.

                        • cgriswald 9 months ago ago

                          Sure. @sokoloff was offering a rhetorical question showing the absurdity of calling a statement in the past a “lie” just because the contents of that statement didn’t come to pass.

                          A falsehood isn’t even a lie if it is spoken when it is actually false unless the speaker knows it is false. Arguably less so when at the time the truth of the statement couldn’t actually be known. Later it was found/determined/decided that @sokoloff would not be an astronaut. So the statement was shown to be false. But that doesn’t retroactively cause the statement to be a lie.

                          Notably pointing out that such statements aren’t lies is not a defense of the subsequent behavior that caused the original statement to become a falsehood.

                          Your response was something of a non sequitur focusing instead on whether a doctor is “allowed” to do that, but whether a doctor is allowed to do that would have no bearing on whether he lied in the past. I got the sense that you were implying that this behavior was bad behavior but to use your example, no defense was made of the doctor breaking his oath.

                          My question used your example of the doctor to reframe @sokoloff’s original rhetorical question. Is a doctor who breaks his oath an oath breaker? Yes. Did he lie when he took the oath? Only if he always intended to break the oath. If you believe he didn’t intend to break the oath at the time he swore it, you have to conclude that he didn’t lie, even if breaking his oath is otherwise undesirable behavior.

                          • Eisenstein 9 months ago ago

                            So your point is that someone must define the difference between a person 'telling a lie', 'giving their word', or 'swearing an oath' in order to make the argument that that person went back on their original principles, because if they say 'lie' instead then we will pick apart that instead of relying on their intended meaning.

                            And my point is that if we dissect the meaning of the language long enough we end up questioning our own existence.

                            • cgriswald 9 months ago ago

                              My point is that these differences are already defined and common knowledge.

                              This isn't on the order of splitting hairs when trying to define something nebulous like consciousness. There would be quite a difference between @sokoloff saying, "I am going to be an astronaut" as a child, and if he were to say "I am an astronaut" now.

                              What is the 'intended meaning'? The poster made a claim that is false. There is no ambiguity about what was said regardless of presumed intent. Any concerns about questioning our own existence seem extremely premature at best.

                              • Eisenstein 9 months ago ago

                                I think the intent of the original comment 'they lied about doing no evil and we should dislike them for it and feel betrayed' is key here. Yes, technically 'lied' is not the correct term, but nitpicking it by using a completely different scenario (a child making a grandiose decision motivated by the nature of childhood) is going from 'wrong term' to 'fundamentally misunderstanding the nature of trust'. I think a better example than any of the ones brought forward would be a loan. Would you trust a child to pay back a loan or to be able to conceptualize the requirements of what it means to commit to doing so? If not why would that be a useful example of honesty in this context? Sure, the child would not be dishonest about the payment, but you wouldn't trust them with it.

                                The parent comment was making a statement about dishonesty in the sense that when an adult makes a commitment, we hold them to that unless we do not trust them, and those were people we thought we could trust. They have gone back on that and now we think they are deceitful because they betrayed our trust. Whether or not they believed it at the time they said it still makes them scumbugs for having changed their mind at a later date.

                                • cgriswald 9 months ago ago

                                  This is not a technicality or a nitpick. The scenario offered was different in order to make it easier to see the error, not to suggest both scenarios are somehow identical in every regard. Your doctor scenario also demonstrates the difference.

                                  Regardless, suppose you did lend that child money and they didn't pay you back. Then suppose as young adults, they come back to you and ask to borrow money again. If they always intended to pay you back and have now matured (and maybe even ultimately did pay you back years late), you'd be far more likely to lend them money again than if you found out somehow that he never intended to pay you back the first time.

                                  There is meaningful difference between "This person committed to something and ultimately didn't live up to that commitment," (or only lived up to it for a certain amount of time, etc.) and "This person lied when they said they were committing to something because ultimately they failed." In one case they changed their mind and perhaps knowingly went back on their word or were unable to live up to their word due to forces outside their control. In the second case abuse of trust was the entire plan. Both of these say different things about the person who violated our trust and whether and with what we can trust them in the future.

    • slothtrop 9 months ago ago

      Ad revenue means tvs priced for less than they ought to be, it's a trade-off for consumers. You could quibble about the externalities but it's ridiculous to suggest there's no upside, for anyone. If that were true they wouldn't sell.

      • Eisenstein 9 months ago ago

        You can't claim something is a benefit for consumers if the consumers are not offered a competing product without the predatory features for more money. Let's put a 'dumb' TV on the market and regulate that 'smart' TV boxes have to say 'this is cheaper because we make most of our profit from it by screenshoting what you watch 100 times a second and selling it to the highest bidder' and see what the market thinks about it.

        • redwall_hp 9 months ago ago

          Also if you buy a TV with no ads or other predatory features, then they push a software update that adds them. You can hardly say the customer was a "rational actor" who made an informed choice if you change their property after you sold it to them.

        • slothtrop 9 months ago ago

          If the demand is strong enough, there will be. No one leaves money on the table. As it stands, it's deemed too risky.

          I'd like another querty productivity phone as good as the BB curve 9320 or Q10 was, and willing to pay, but it probably won't happen.

          • Eisenstein 9 months ago ago

            You are presupposing that people are going to be omniscient. Without knowing the downsides of the thing they are buying that is cheaper, there will never be demand for something more expensive that doesn't have them. My argument is that if we put on the box what the thing does, many fewer people would buy it, and there would be demand for something that doesn't have those 'features'. It is easy to justify after the fact which is why they just do it and when it becomes common enough people stop caring because they already invest money into it.

            'The market is the solution' is true only as long as human factors are seen as market distortions and mitigated through regulation.

      Under end-stage capitalism, the one and only thing driving the market is maximal extraction of all conceivable value within a financial quarter. There are no other concerns. The market inherently cannot consider any other consequences or benefits beyond short term gains at any cost.

      Flowers can’t be eaten. They’re just for someone to look at. Heck most people probably don’t even look at them and buy it as a part of a ritual or formality. Does it mean the flower industry is of no benefit to society?

      Most things we do are in the end just burning energy to create, move and destroy things in the process. The guys who benefit from ads buy salad from shops employing people. It’s arguable that anything that increases economic cycles is of at least some benefit to society. That’s the advantage of capitalism.

        • card_zero 9 months ago ago

          It's a curious thing, though. We have this idea that economic activity with consent is beneficial, and without consent it's theft and harmful. But this is a rule of thumb. The vast majority of things people do are - variously - pointless, inefficient, sentimental, superstitious, idle, crazy, and otherwise indefensible except by the reasoning that it's our right to do what we like with what we own, what we've earned and paid for. This we call wealth, and having it makes us feel happy and secure, but to actually centrally analyze it and assess its usefulness would be a bad thing. That would only make its value evaporate. We want to be free to do dumb things, and not to be told.

        That's actually the perfect description of why 'content creators' aren't called artists. They're not creative, they're regurgitative.

        Originality is an art unto itself.

        What you are right about, however, is the profit inherent in bland copies, which means there's a market out there consisting of dumb, easily satisfied cattle, to be milked by the lazily regurgitative bottom feeders that know only 'what's trending' and have said subscribe! more often than they've had hot meals.

        • card_zero 9 months ago ago

          I read somewhere - I think in a previous thread, about the New Scientist version of this story, where somebody posted text from a site selling ACR services - that the real interest lies in empirical measurement of what adverts you're seeing, and the context that you see them in is of only secondary interest. I guess the ads you see could be matched up to what you buy. It's an "are our adverts working on this person?" question (and thus "can we show that our advertising service is worth buying"), more than a question of "what advert do we send this person next?"

    • card_zero 9 months ago ago

      What happened to stop you answering, were you kidnapped by LG?

    • xnx 9 months ago ago

      Could ACR be used against its creators by creating a tool to detect and automatically block-out advertisements? (e.g. via an HDMI pass-through) There should be enough tell-tale signals (text, sound, number of scene changes, etc.) to distinguish advertisements from non-ad content.

    • card_zero 9 months ago ago

      Why do they (LG and Samsung) not fingerprint things streamed from a phone, but do fingerprint anything coming over HDMI? And why do they fingerprint their own FAST services, don't they know what they showed already?

      • bottom999mottob 9 months ago ago

        I'm trying to find more information about these 2 companies fingerprinting or hashing anything coming over HDMI. Do you have sources? I thought disconnecting my smart TV from internet to be enough to stop the transmission of any ACR data. My concern would be if they store any ACR data locally and queue it for data collection vs if they stream it.

        • Eisenstein 9 months ago ago

          It is in the paper:

          "We find that: (1) ACR network traffic exists when watching linear TV and when using smart TV as an external display using HDMI"

          • card_zero 9 months ago ago

            But also that they send it in batches every 15 seconds (Samsung) or every minute (LG). The question is whether an offline TV will lie in wait to send all the data it collected in one massive batch, when and if it gets online. That wasn't tested.

      • NegativeLatency 9 months ago ago

        Might be easier to aggregate data if it’s all coming in in a similar way?

        • card_zero 9 months ago ago

          Coming back to this, I see it's in the paper. There's a mention of copyright, and then:

          > Netflix prefers to have ACR deactivated during its streaming “in order to preserve the integrity of its subscribers viewing experiences and maintain sole control over measurement of its viewership” (Verance, 2020). The same reasoning applies to FAST channels, which LG and Samsung consider to be ”aggregator apps” (Wolk, 2023), where providers may have agreements restricting ACR usage.

          In other words, FAST comes from other providers, who may complain. Random content over HDMI doesn't. However, this doesn't explain why they ignore video streamed from phones (tablets, laptops, etc) wirelessly.

  • lifthrasiir 9 months ago ago

    That's concerning. To be clear, I once worked on a company that developed an audio-based ACR technology to be used in conjunction with a secondary device that users would turn on at their will. Anything more invasive would have been substantially challenging in legal aspects so that was the status quo more than 10 years ago. So it's new to me that not only ACR is somehow pervasive in "smart" devices but also they even don't care whether they are really being used as a television (which has no other interaction mechanism in principle, and ACR is not only for ads).

  • bottom999mottob 9 months ago ago

    • slothtrop 9 months ago ago

      It may happen. I think at present there is too little demand for comparatively expensive tvs that respect privacy. The tech is in a phase of diminishing returns, as televisions from over a decade ago still suit most people fine, and don't break that easily. Tech people were just turning off features they don't like (until, of course, that's no longer possible). But alongside the price-point, manufacturers are also playing a game of chicken expecting everyone to continue purchasing despite invasive features. At least among tech-oriented people it's possible that sales will slow down, but that might not matter enough for their bottom line to offer an alternative. There may be room for a competitor to try selling boutique tvs, but it's risky. "the market provides", but the demand needs to be strong enough.

    A reminder that the existence of the advertising industry is a tax that drives up the cost of everything that you buy, because every dollar spent on advertising is a dollar that does not actually improve the product in any way, and yet must be recouped by increasing the price of the product.

      > A reminder that the existence of the advertising industry is a tax that drives up the cost of everything that you buy, because every dollar spent on advertising is a dollar that does not actually improve the product in any way, and yet must be recouped by increasing the price of the product

      I am not going to try to argue that advertising is good or anything, but I don't think your economic argument is accurate.

      If a company didn't have to spend anything on advertising, they wouldn't use that money to improve their product or to reduce the price; the money would go towards profit.

      So many people seem to think that prices are set at "expense + fixed profit margin = price" but that is not how any company sets their prices. The ONLY reason a business is going to lower prices is because they think that is the way to increase their profit. They aren't going to lower prices just because some cost goes away.

      • idle_zealot 9 months ago ago

        The idea is that they would have to spend that money on improving the good/service or reducing the price in order to compete. Currently more money goes to competing for your attention than on competing on merit.

      • bonoboTP 9 months ago ago

        In an efficient market, competition would drive prices down to reach quite thin profit margins. Of course there is all sorts of friction, change in conditions, inertia, upfront costs, risk etc that reality isn't ideal.

      • gljiva 9 months ago ago

        If advertising is giving an expected edge over competition bigger than price decrease, then the advertising will be used in sort of an arms race that could have been a competition in giving the best product for the least money instead.

        Still, even if there is no immediate price decrease for the customer, I would be much more satisfied if all the money went to the maker(s) of the product and well-investing shareholders than someone who provides no value and could have been working on something productive instead.

    • moandcompany 9 months ago ago

      In the case of television screens, the net profit margins on sales of these devices are in the single-digit percentages. Fairly thin, around 4-7%. Higher-end products, such as cutting-edge flagship products (e.g. 100"+ MicroLED television screens) will have higher margins, but lower production yields, and orders of magnitude lower sales volume. These products don't need to be replaced year after year, and most buyers are not selecting a product based on the technical specifications and performance, rather the screen-size per dollar (or whatever currency used) and other factors such as aesthetic appeal of the device in the home environment. The average lifetime, before replacement, of a television screen in North America is somewhere around 5-7 years, and you don't need one in every room of your home or living space.

      The commodification of screens from both the production side (i.e. newer entrants to the market from Chinese manufacturers) and from the content portal side (i.e. Roku, Google TV, Fire TV, etc) is a major strategic problem for the television brands you are probably most familiar with. The forementioned examples of content portals are coming from companies that are fundamentally based around advertising, and the companies that were traditionally about manufacturing realized that the advertising revenue opportunity was too good to give up. They are trying to grow their revenue, and profitability, and see that they won't be able to do so from their original core businesses. This is also why you're seeing all of these "FAST" (Free, Ad-supported Streaming Television) services popping up from the tv manufacturers themselves.

      Vizio, for example, was a value-oriented producer of televisions and related products. In 2021, as Vizio became a public company, they disclosed that they make more than twice the profit from their advertising/service business than their device sales (https://www.theverge.com/2021/11/10/22773073/vizio-acr-adver...). Walmart is now acquiring Vizio for that business and the opportunity to collect customer data (https://corporate.walmart.com/news/2024/02/20/walmart-agrees...).

      Roku is another good focused example because they are a publicly traded company and you can analyze their income statements and business model. Their hardware devices are basically being sold at cost or at a loss so they can seed the market and create an audience (i.e. their inventory) for their high-margin advertising services business.

      Google and Amazon also want a large piece of this pie. Apple is starting to show that they want advertising money too.

      We are also seeing cases where the television devices themselves can be produced cheap enough to be given away to users that opt into advertising (e.g. Telly: https://www.theverge.com/2023/5/15/23721674/telly-free-tv-st...). When this dynamic is economically viable (i.e. give away the hardware, make the money via ads), you can see how big of a problem traditional television device manufacturers have.

    • ethbr1 9 months ago ago

      Can a capitalist society operate without advertising? How are people to learn about products and services that are available? Yet today poorly targets ads waste the time of everyone involved. If ads could be made relevant without invading your privacy would you be against that?

      • kibwen 9 months ago ago

        I'll list three kinds of ethnical advertising:

        1. If I have an interest in a field (say, electronics) and then I attend a conference or gathering that's relevant to that field (say, CES), and then you buy a booth at that conference in order to hawk your wares, that's A-OK. The crucial difference is that I willingly understand the context--I'm going to be going to a place that's all about having people sell me things--and that advertisers are not running roughshod over a space where they don't belong. Consider this "pull-based" advertising rather than the "push-based" advertising where ads get shoved in your face every second of the day everywhere you go, even when you're just trying to live your life.

        2. Organic word-of-mouth referrals. In an online, AI-infested world, the "organic" part is increasingly hard to come by, but if someone that I trusts tells me that a product is good, that's great and welcome. Crucially, their reputation with me is on the line if they turn out to be wrong or financially compromised.

        3. Simple indication of presence. If you have a shop, you're allowed to have a sign on the front with the name of your shop... within reason. Don't push it. Billboards should be banned.

        • czl 9 months ago ago

          100% agree with your three points.

          When you "visit" Google / Facebook / YouTube / other online properties do you think you are "going to a place that's all about having people sell me things"?

      • bonoboTP 9 months ago ago

        Do you mean when an entirely new product category is invented and I didn't even know it's useful to me? Because that's kinda rare.

        In other cases such as buying a shoe or a can of beer or a fridge or a car, I just go to the website or the physical store that sells it and I compare the products and buy the most suitable one.

        This way purchases would be prompted by an actual need, like when my shoes are worn out, I look to buy new ones instead of it being pushed on me through ads when I don't even need it.

        Usually the existence of the ad doesn't mean that it's the best in its category. Why would it be in my interest to be following ads instead of my own research?

        Also this gotcha is decades out of date. Today's ads are rarely about the features or suitability of the actual product. Instead they sell a vibe, a lifestyle feeling, they create positive emotional associations in ways orthogonal to the product's attributes. Think Coca Cola with celebrities etc. After all, how would I otherwise know I need a can of coke if the trendy singer didn't tell me about it, right?

        • AStonesThrow 9 months ago ago

          I generally find that the ads I see are for things that I definitely don't want and shouldn't purchase, and it's just them pouring bucks into the effort to get in front of my face and wear me down.

          Consider that you should never accept cold-call sales or offers under typical circumstances; I make notes on the ads I see in order to blacklist them, essentially.

          The good deals are found by my seeking them out, doing research, asking questions. Knowing a brand reputation apart from marketing. Discerning things like corporate culture, attitude, politics, intended market or audience.

          So many products and services are made on the basis of shoveling crap to make a profit, or supporting some cause or crusade, and the more I can pierce the veil, the better I feel about where my money's going.

      • emptybits 9 months ago ago

            > If you do not know a problem is a problem why search for a solution?

            Exactly, I would NOT search for a solution. No sale. Less consumption.

            In most cases if you do not know a problem is a problem, then it is actually NOT a problem.[1]

            Advertisers' jobs are to convince you otherwise. e.g. You need our pill. You need our gadget. You need our clothing or cosmetic. Advertising does not care about your best interest. Advertising tries to make a sale and advertising is considered successful if a sale is made even if no problem was solved.

            [1] There are some exceptions. Serious medical conditions, for example. I don't think most people object to altruistic advertising campaigns to educate people about genuine health problems and their solutions. But I don't think that's what we're talking about here.
