speaking of TV for children

I was reading elsewhere about how the early episodes of Sesame Street would no longer be considered suitable for children. Some of the problems:

1. Some of the muppets are smoking pipes in the early shows.

2. Kids ride bicycles without helmets. (So did we all in that generation.)

3. In one sketch Gordon meets a little girl on the street, invites her to his apartment, and walks there with her, hand-in-hand.
