I don't have TV, but I let my son watch TV. It's just stuff I've checked out, like "Curious George" on Netflix, or the 1960s "Batman" TV show that I have on Plex.
Sure, he's heard about Mighty Morphin Power Rangers from his friends at pre-school, but his mother and I think it's too intense for him right now.
I don't let my life be ruled by what other people think is popular, I'm certainly not going to let my child be raised according to that standard.
