My kids were all reading fluently before age three, and none of them watched a lot of tv. My current wee one didn't watch anything before two, except Signing Time dvds. She did know many signs and the whole ASL alphabet before turning two.
If I think on it more, my earliest reader started watching Sesame Street in the mornings when I was getting his brother ready for school when he was about 11 months. That was all he watched for the first two years, and it's funny I hadn't thought about it much before. I was stricter with the other kids, but guiltily resorted to the "electronic babysitter" when in a pinch. School mornings were tough with my oldest, who has AS. We didn't know why transitions were so hard for him at the time.
