The channel was launched on December 2008, after all classic animation programming from Warner Bros., Hanna-Barbera and MGM were removed from Boomerang Latin America, to center the network towards the teen audience, and replacing it with live-action programming instead.

Tooncast follows the Boomerang US old channel line-up, which aired classic cartoons. Old Cartoon Network commercials are also broadcast on the channel, such as “Cartoons That Never Made It,” Cartoon Network Groovies, and Boomerang Shorties.
