I was born in ’99, so I grew up in the last age of CRT TVs. I’m wondering why they were built to have curved screens. It’s not like flat screens weren’t a thing, because films were projected onto flat screens in movie theaters until IMAX became a thing. But I wonder what about cathode rays made curved screens a necessity until plasma, LCD, and LED televisions came about.

Becuase they were lit by a cathode tube. (CRT = Cathode ray tube) which needs a convex end-point. remember the “degauss” button on CRT’s, and [this](https://en.wikipedia.org/wiki/Degaussing#/media/File:Degauss-in-progress_at_Dell-Trinitron-monitor.jpg) happened. sometimes pixels got stuck due to magnetic aberrations. the convex screen was necessary at the time for CRT to work.
