YouTube has inked deals to start offering full length TV shows. The Google-backed company intends to go head to head with Hulu, which has several deals with networks to carry TV shows.
These kinds of alternatives are quickly making it quaint to sit down in front of the TV at a certain time on a certain day to watch a particular show. I'm a fan of the Sarah Connor Chronicles, but I could not tell you what network it is on, what day new shows air, or what time it plays. I simply go to the iTunes Store when I have a little extra time, pay $2, and watch the show at my convenience. For that $2, I enjoy it without commercial interruption.
Cable and satellite TV are rapidly becoming anachronisms.
