    A couple of interesting takeaways:

    - Pre-LED Jumbotrons used CRT pixels called "Trinilite" elements. This was a proprietary Sony technology where each sub-pixel or "cell" was a miniaturized CRT assembly. Each resolved one pixel each.

    - A "maximum" NTSC configuration consisting of 40 units wide would result in a horizontal resolution of just 640 dots.

    - The display needed a calibration using a “Screen Alignment Unit” (the JME-SA200). This unit used a remote modem chain involving a "cellular phone" and "digital data card." This means that Jumbotron techs could dial in over 1998-era mobile networks to geometrically align a stadium-sized wall of vacuum tubes as they sat in the middle of said stadium.

    I also found the format of the manual interesting, because it follows the same style of consumer-grade Sony devices from that period.

    Off-topic, but this ongoing trend of brands getting TLDs is really starting to infuriate me. It's not what TLDs are for! Sony is a Japanese company, so it should use sony.com or sony.jp.

      There's no inherent reason to restrict the number of TLDs. The best way to combat rent seeking from registries is to allow any organization that has the technical capability to operate a registry.

        Why do companies and organizations get special treatment over regular people? I think a simpler fix is just to ban any companies that register domains from squatting on them.

          Were regular people prohibited from applying for TLDs when applications were open?

          Not that I know many people who would have been interested in paying the fees.

      That’s not what the ICANN thinks, and this started in 2012:

        Any idea why Google and Microsoft and Apple don’t yet have TLDs then?
