TV isn't dead. But "television" is.
My "TV" has a receiver but most of the time, even when I watch something that is "broadcast" (air or cable), I am using the tuner/remote from my DVR or CVR.
So my "TV" doesn't need a receiver of its own (my DVR will even let me record one program while watching another).
Which brings up its other role, as a monitor to display DVDs, laserdiscs, videotapes (VHS and 8mm)...
A lot of people are watching tv shows/concerts/clips on YouTube and other multimedia website. Is that "tv" or "PC"?
The distribution method doesn't really matter when you examine what is being watched.
If someone watches The Sopranos or 24 on DVD (from Netflix or Best Buy) instead of on Fox (live or Tivo), are they still "watching tv"?
Being dead is not the right term to use...revolution would be better. Face it...to have high quality written shows like Lost, Desperate Housewives, and Battlestar...which are lightyears above where TV was in 1995 for scripts...we are watching consumers demand more.
We will likely see a British-based channel operating amongst the top 10 channels in the US within a couple of years...simply doing something different. We will see reality shows go even further than what we see today. All of this...is revolution. TV isn't dying...its just trimming off the excess and getting leaner.
