When I was really young I used to watch Fox Kids and Kids' WB. Later on I got into Toonami after my family finally got a cable package that included Cartoon Network.

For me, it was the after school block of He-Man, GI Joe, and Transformers.

I watched Fox Kids and Disney Afternoon. I feel like there were more, but they didn't always have specific names. ABC ran these inbetweeners through multiple shows.

I used to love watching Cartoon Network's "Super Chunk" block.

That reminds me that Cartoon Network has had a lot of blocks. I was a big fan of Cartoon Cartoon Fridays, with their original shows, and Late Night Black & White, with shorts from the 30s and 40s
