History
Warner Bros. Animation as it is known today began in 1989, when Jeanette MacCurdy, who was in charge of productions at Hanna-Barbera, left to spearhead the effort in revitalizing the studio for a modern era. She brought along fellow Hanna-Barbera employee Tom Ruegger, who had been the showrunner of A Pup Named Scooby-Doo at the time, to oversee the production of the Looney Tunes spin-off Tiny Toon Adventures, a collaboration with Steven Speilberg's Amblin.
