What if William Hanna and Joseph Barbera worked for Warner Bros. after leaving MGM and retained the rights for Tom and Jerry?/Tiny Toon Adventures

Tiny Toon Adventures is an American animated comedy television series that was broadcast from September 14, 1990 through May 28, 1995 as the first collaborative effort of Warner Bros. Animation and Steven Spielberg's Amblin Entertainment after being conceived in the late 1980s by Tom Ruegger. The show follows the adventures of a group of young cartoon characters who attend Acme Looniversity to become the next generation of characters from the Looney Tunes series.

The pilot episode, The Looney Beginning, aired as a prime-time special on CBS on September 14, 1990; while the series itself was featured in first-run syndication for the first two seasons. The final season was aired on Fox Kids. The series ended production in 1992 in favor of Animaniacs; however, two specials were produced in 1994.

Plot
Tiny Toon Adventures is a cartoon set in the fictional town of Acme Acres, where most of the Tiny Toons and Looney Tunes characters live. The characters attend Acme Looniversity, a school whose faculty primarily consists of the mainstays of the classic Warner Bros. cartoons, such as Bugs Bunny, Daffy Duck, Porky Pig, Tweety, Yogi Bear, Boo-Boo Bear, Huckleberry Hound, Tom Cat, Jerry Mouse, Sylvester the Cat, Wile E. Coyote and Elmer Fudd. In the series, the university is founded to teach cartoon characters how to become funny. The school is not featured in every episode, as not all of its storylines revolve around the school.

Like Looney Tunes, the series makes use of cartoon violence (e.g. anvils falling on someone, liberal use of explosives) and slapstick. The series parodies and references the current events of the early 1990s and Hollywood culture. Occasionally, episodes delve into veiled ethical and morality stories of ecology, self-esteem and crime.

Occasionally, other characters from other Warner Bros. shows like The Flintstones, Scooby-Doo and Top Cat and DC Comics characters would make special appearances.
