Yesterdayland has saturday morning cartoons by decade (via Chutler at 13 Labs). I chose the 70s (which took me up to 8 years old). Of interest, I give you Ark II, Superfriends, Tarzan, Flash Gordon, and Hong Kong Phooey.

This is my domain, and I protect those who come here, for I am Tarzan, Lord of the Jungle.
