IMO TV is simply not necessary.

I lived for years without TV and found out that during disasters radio had more, and more frequent, local news. The TV stations were all regional and neighbors were actually less aware of what was going on locally watching TV. Yes, TV has pretty graphics but a much lower information density. Watching TV is also a fairly singular activity. I can do real work and listen to the radio but watching TV, not so much. I would save precious resources like gasoline for more important things than keeping the boob tube lit.
