I remember back in 1994 or 1995, my girlfriend and I sat in the "home theater" at Circuit City and marveled at the 32" Flat Panel TV (that must have been "only" 3" thick) for $10,000, playing something that looked really good compared to the rest of the tube TVs on display.
Thanks for the efforts of the early adopters, willing to plunk $10,000 for a TV that had the capability (720p capability had been surpassed long before TV's became mainstream), but no source of content, I was able to afford to buy my own first 42" Flat Panel (LCD) TV in 2004 for $600, and then a 55" LED for $400 in 2012.
6 TV's in the house on FiOS and we only pay $4.99/month to connect them all!!! Power to the CableCard and WMC7!!!
