Yeah Cartoon Network didn't show up til the 90s I think. Though I've heard rumors the USA Cartoon Express became Cartoon Network.
USA Cartoon Express was on from 1980 to 1998.
In 1991, Turner Broadcasting purchased Hanna-Barbera and launched Cartoon Network a year later, thus taking a chunk of Cartoon Express programming with it. The only Hanna-Barbera programs remaining on the Cartoon Express were Scooby-Doo, which didn't leave the Express until 1994, and The Smurfs, which stayed until 1995. In the fall of 1994, USA moved Cartoon Express from weekday afternoons to weekday mornings, in addition to its Sunday morning lineup ,and revamped the entire look of the block from an orange locomotive motiff to a silvery bullet train motiff.
