I could go without TV if it weren't for my regular shows which I watch. There are quite a few of those though. eg. Good News Week, The Gruen Transfer, Spicks and Specks, Bones, Castle, Big Bang Theory, Lie to Me, NCIS, How I Met Your Mother and United States of Tara. But if it was just a week I could seriously go without any of the 3 options and it wouldn't be overly hard. It's just one tiny week people!
There are so many good shows I used to watch which I can only see on dvd now :( But I count that as using TV as well, and playing xbox. So I do use my TV quite a bit I suppose.
