When I bought my first house, I got Comcast cable internet and they guy had to put a filter on to block the TV and just let the internet signal through. Or at least he would have, but he couldn't find one in his truck. Years later, I got around to plugging my TV into it and found that I had full access to all of the non-paid channels, and I'd missed out on half an adult lifetime of free television. Can't say I missed it, though.
