I remember around that time period seeing widescreen CRT TVs at one of the big department stores at the mall (US).
Over the years I had come to question my memory, but I'm glad this thread has informed me that such TVs really did exist.
I'm not sure what the appeal would have been really. But I guess they could have had scaling options that made them useful with letterboxed video tapes and laserdiscs, as mentioned. I think I just remember them showing stretched out versions of that day's football game.
The addresses given in the ad imply it would be a US/Canada market TV. From the TVs I've seen, I think S-Video was typically the best input offered on our TVs in the mid to late 90s. I'm not saying component or RGB were impossible in the mid-90s, but I think it must have been very rare at best. I think component started to be common in the early 2000s, probably in response to DVD players. I haven't personally seen RGB on anything in the US. It existed, but it was never a common standard here.
In an age before DVD players, I'm not sure what consumer devices in the US market would have supported component or RGB outputs. All I can think of are some game consoles which had RGB but only because it was useful in Japan and Europe.
I'm still fond of CRT TVs for playing old game consoles. The graphics were designed for CRTs and they also play better thanks to no lag. I can do without the really big TVs but I hope to always have a good CRT in the ~20" range.
