When my kids were little, I forbid them to watch Linda Ellerbee or Nick News. Just over Christmas break my son, who is now 21, said, "Mom, remember when you never used to let us watch Nick News?" I said, "That's why you turned out to be such a good conservative."
When Nickelodeon allowed that Tick tick tick ad to be on & it scared my daughter that was it for me. No Nickelodeon here.
