What-A-Cartoon!, also known as World Premiere Toons or WAC for short, was the mid-1990s animation showcase that appeared on the Cartoon Network. It served as the launching point for several original cartoons including Dexter's Laboratory, Johnny Bravo, Cow and Chicken, Powerpuff Girls, and Courage the Cowardly Dog.

WAC was an animation project guided by Fred Seibert, the former president of MTV Networks who served as the president of Hanna-Barbera Productions prior to founding Frederator Studios, and Betty Cohen, then Cartoon Network's president and guiding force in the network's overall design. She also performed similar duties at Nickelodeon creating that channel's revamped look in 1985.

The first World Premiere Toon to premiere was "Meat Fuzzy Lumpkins," which made its world premiere on February 20, 1995. The series of cartoons made a simulcast airing on Cartoon Network, TBS, and TNT.

Cartoon Network's What-A-Cartoon!, which was assembled into a half-hour series, The What-A-Cartoon! Show (later renamed to The Cartoon Cartoon Show), featured and produced over 45 brand-new seven-minute cartoons, as well as 38 new characters.

There was also a large number of animated shorts created by several cartoonists such as: Genndy Tartakovsky (Dexter's Laboratory (4 cartoon shorts)), David Feiss (No Smoking, which introduced the siblings Cow and Chicken), Van Partible (Johnny Bravo (2 cartoon shorts)), Craig McCracken (Meat Fuzzy Lumpkins, which introduced The Powerpuff Girls, and Crime 101), Butch Hartman (who did a number of one-shot shorts, including Pfish and Chip and Gramps), Seth MacFarlane (Larry and Steve, which were prototypes of Peter Griffin and Brian of Family Guy), John R. Dilworth (whose Oscar-nominated Chicken From Outer Space introduced Courage the Cowardly Dog), and countless others. Also included were works from veterans like William Hanna (Wind-Up Wolf and Hard Luck Duck), Joseph Barbera (shorts featuring The Flintstones' Dino), and Ralph Bakshi (Malcolm and Melvin).

The What-A-Cartoon! experiment introduced many of today's top animation talent and was repeated several times. A similar program was introduced on Nickelodeon, where Fred Seibert launched Oh Yeah! Cartoons, which included The Fairly OddParents, ChalkZone, and My Life as a Teenage Robot, which later became Nicktoons. The Fairly OddParents has since become one of the most highly-rated Nicktoons, second only to SpongeBob SquarePants.
