I would lean toward not having one. I used to watch tv(possibly addicted) as a child. I even had a tv schedule. I came home from school did my homework and from 6:30 to 10 11:00 every night I would watch tv. I continued to watch tv until I went off to yeshiva in Israel where I took dvds of my shows with me. Now that I do not watch tv any longer I really regret that I had the opportunity to do so.Much of the shows that I watched inappropriate content is stuck in my head (ex. FRIENDS or Simpsons, etc)and I really wish I could get it out. Do your future kids( and yourself) a favor and do without the T.V. Please take my word for it.
Ps. and as I hear it : the content is just getting worse and worse.
If you really need entertainment rent some dvds of I love Lucy and other 50s shows (70s are a little risky) and watch them on your computer
