Yeah but I don't know anybody who actually did that. Most people get a new TV every 5-10 years anyway, and by then, plasmas were affordable and widely available.

There were also...I remember a certain class of rear projection TVs from around the turn of the century that were a lot more compact than the gigantic box type from the 90's. Similar technology but just not as boxy, often available in 16:9 that weren't plasma or LCD panels.
