Hanna-Barbera Enterprises, Inc. was an animation studio that impacted and dominated television since it was founded in 1944, by William Hanna, Joseph Barbera and George Sidney. Also under the names of Hanna-Barbera Productions Inc., and Hanna-Barbera Cartoons, Inc., it's main function was to produce films and commercials. It went on to provide a powerful and lasting impact on television animation. Furthermore, a great many of the characters originally created by Hanna and Barbera for the small screen have crossed the boundaries into film, books, toys, and all manner of other media, becoming virtually ubiquitous as cultural icons. The name Hanna-Barbera still exists under the umbrella of Warner Bros. Animation for all historic proprietary material and to market "classic" associated material.
