We got our first family TV in 1949, so my cartoon memories are mostly 1950s, plus some evening "adult" cartoons from the early '60s. And we still had Saturday matinee children's movies at the local theatre, that opened with a Loony Tunes cartoon or 2, to much cheering from all the kids. And Saturday morning was almost entirely cartoon shows on TV, along with some live kiddie shows hosted by everything from the wacky Soupy Sales to the creepy Vampira.
From the '50s we had Crusader Rabbit, and recycled theatre cartoons, a lot of them from the 1940s, like Tom & Jerry, Popeye, Superman, Heckle & Jeckle (a pair of magpies), Mighty Mouse, and older Loony Tunes.
And a peculiar original kind of participatory cartoon called Winky Dink. Animated with a minimalist background, almost like early computer games, little Winky encountered all kinds of challenges, which the kids at home were supposed to solve by drawing helpful things directly onto the TV screen for him to use! Following brief screen prompts that appeared you drew ladders, stairs, boats, ropes, foot bridges, and so forth, that you then erased for the next scene.
For that purpose your parents were supposed to buy you a Winky Dink kit, consisting of a heavy electrostatic sheet of clear plastic that went over the TV screen, special easily-erased crayons, and a wiping cloth. Problem was, kids without that kit simply drew directly on the glass screen with their own regular Crayolas.
And when Mom tried to remove the tough waxy crayon with too much liquid cleaner (remember that TVs were still a new thing in the mid-1950s) the TV could short out in sparks. Or the kids would try too hard to erase the Crayolas themselves, or simply get excited with the action and start pounding the screen. Which would crack, or even explode in a few reported cases. Winky Dink was taken off the air amid a flurry of lawsuits. I lost interest myself when I quickly realized that Winky would climb a staircase whether I drew one for him or not.
Evening cartoons included the Jetsons, one of my favorites. And the Flintstones, that didn't much captivate me. Walt Disney himself would personally introduce a Sunday evening weekly show that often featured some of his cartoons, but you couldn't see them elsewhere on TV. After 1962 when I became a teenager the TV cartoons for kids fell off my viewing menu, so that I don't know the majority of the ones being mentioned here. I guess I'm now at the other side of what in the mid-1960s we dubbed the "generation gap".
