USA Cartoon Express is a programming block for animated series on USA Network, airing from late 1982 to September 15, 1996. The original line-up consisted of Hanna-Barbera shows before branching out into other cartoon shows. It aired various incarnations of Scooby-Doo from 1990 to 1994, only one of two Hanna-Barbera shows (the other one being The Smurfs) to be included on the block after Turner bought the studio and launched Cartoon Network in 1992.
- The opening and closing titles for the Scooby-Doo, Where Are You! episodes, What a Night for a Knight and A Clue for Scooby Doo, boasted different theme music composed by Hoyt Curtin, with a spooky feisty tune which is an extension of the sub-main title theme, complete with intro, bridge and close. From the third episode (Hassle in the Castle) on, the theme song was now a composition done by Ted Nichols, following from lyrics written by David Mook and Ben Raleigh. The original theme was unheard for many years until the show's resurrection on USA's Cartoon Express in 1990, and was heard during its run on Cartoon Network, until Turner decided to remaster all the episodes in 1998.
The following were bumbers shown in the summer of 1990. While Shaggy Rogers and Velma Dinkley appeared, Fred Jones and Daphne Blake didn't. Although two kids in the second bumper (down below) did have a red-haired girl wearing pink and a blond-haired boy wearing white.
