to about 1971! I remember just about all of those shows depicted from that time, and nearly all of the commercials. Some time around 1972, though, my mom started kicking me out of the house on Saturday mornings just as the "New Pink Panther Show" was coming on, so I don't really remember any shows after that.
2. What's really frightening is that I remember damn near all of those clips.
I used to get up at 6:30 so I could catch "Skippy" (kangaroo in Australia) and "Flipper" before the cartoons started, and one of the first on was the original Kimba (not the shitty remake). H.R. Puff-N-Stuff and Johnny Quest were two of my other favorites.
