Also, isn't power consumption the reason plasma is less popular than LCD? It seems to me that plasma has better picture quality, but uses more power.
That was one of the reasons. I think potential burn in (though really image retention, since it's not permanent burn in) is the other major cause.
Plasmas at the time were LARGER, CHEAPER, and looked better. I think it's only now that we're getting into gigantic TVs (70 inch and above), that plasma can't do.. I also think it can't do 4K, or not easily. Those seemed to be reasons companies have stopped making plasma.
Also, from what I've read (popular press, online reviews), the more recent plasmas (not VERY recent, as in the last several years at least) were much more energy efficient.. The huge discrepancy compared to LED was, I think, based on early plasmas.
(I have a 42" plasma that I got when my CRT died several years ago. So I guess I'm sort of biased, but I basically went out and bought a TV very quickly, and plasma seemed to be the best and cheapest at the time.. I am someone who cares about power usage, but my overall electricity bill is low anyway -- $20-$30.)
