I mostly use tv as background noise.
I rarely actually watch what's on TV, and instead mostly use it as background noise, while looking up and watching bits here and there, but going back to what I was doing. I've done this ever since I was a kid and loved to listen to the TV as I drew, and it seemed to oddly help me concentrate and even fuel my imagination for my drawings. Now, it still helps my concentration. I also just don't like it too quiet and like the background noise it offers.
