I don’t “watch” TV anymore. It’s more of a “listen ” as I have it on while I’m on the computer.  When I do watch, it’s OnDemand. Paul Graham (a  programmer/venture capitalist/the guy that made Yahoo! Stores possible) wrote an interesting article, “Why TV Lost”

From the article,

“Twenty years ago people noticed computers and TV were on a collision course and started to speculate about what they’d produce when they converged. We now know the answer: computers. It’s clear now that even by using the word “convergence” we were giving TV too much credit. This won’t be convergence so much as replacement. People may still watch things they call “TV shows,” but they’ll watch them mostly on computers.

Now would be a good time to start any company that competes with TV networks. That’s what a lot of Internet startups are, though they may not have had this as an explicit goal.”
