Oh, Ocicat, you had to go say Pinky and the Brain. Sigh. I love that cartoon. Narf.
Seriously, though, I think some of the cartoon that don't hold up, ok, maybe all of them, were the ones that were built around product placement. He-man, She-ra, Transformers, Go-bots, etc.
The books, however, were only meant to sell themselves.
Its just a thought.
