Don't call it a "television." Call it a "sorcery box."
We take the television for granted. They're everywhere now, we turn them on and they just work. But for a vast majority of human history, an HDTV would be considered serious magic.
Put a show about dragons on a 21.6" screen back in 1066 and you probably could have emptied London. Heck, put on Sesame Street and you could have possibly avoided the entire Dark Ages! Don't just look at the 700:1 contrast ratio and see a normal, regular, everyday technology. Think for a second at what a marvel you've brought into your house! Any age but this one, it would have been a miracle machine!
The 1200s? Load a JPEG in the USB 2.0 port and tell them you've captured their soul. You'd have suckers lined up for blocks paying you to "return" it. The 1500s? Imagine the sort of video game that Shakespeare could have written! You can be sure it would have taken full advantage of the easy-connecting computer and console inputs. Of offer 1930s era Philo Farnsworth ten minutes with the HDMI input and see how he'd weep with joy. Even the semi-recent '60s generation would have had their minds blown watching Hendrix and Lennon in a 700:1 contrast ratio.
This Emerson 22" 720p LCD HDTV isn't so much an "extra set for the bedroom" as it is a technological miracle. And maybe if you weren't so busy watching The Big Bang Theory you'd know that. Jerkface.
