The room that I use the computer on has a two birds--a green parrot, and a cockatiel. They both like to watch television(or so I've been told). Because of this, I leave it on cartoons (Usually) Nick at a loud volume. However, once Spongebob's voice begins to give me a headache I turn it off.
For the most part, I am on my computer though. Why?
I can watch -anything- and play a -lot- on my computer for free. Television costs money due to cable bill, electricity, etcetera...
Also, games are a lot cheaper on the computer, albeit less entertaining for the most part (If they're Flash). I will however go out and buy a new game or two if I see them as good or they have good reviews. I'd say my ratio of time on computer spent to time on television is about 8:1.
