Do you think that cable/satellite TV is expensive?

My cable bill is $159/month and I want to pay less. I was thinking of getting rid of payed TV and watching videos from my computers instead, along with broadcast TV. Does anyone do this?
@Candle - That's what I was thinking about doing. I usually just listen to the TV while I'm on my computer anyways. I have enough PC's to connect one to each TV in my house to make it an online entertainment center or home theater system. I was wondering if there's enough content and if it's easy to find on the internet. Is Hulu free or would I have to pay?
You guys/girls are the best for pointing me in the right direction with your helpful input. I live alone in the house I bought and i don't have much money after paying all of my bills. This seems like a good way to cut out almost $2,000 a year from my bills. Thank You so much.
