Hanna Barbera.

Hanna-Barbera Productions, Inc. was an American animation studio that dominated American television animation for nearly three decades in the mid-to-late 20th century.

The company was originally formed in 1957 by former Metro-Goldwyn-Mayer (MGM) animation directors William Hanna and Joseph Barbera (creators of Tom and Jerry) and live-action director George Sidney in partnership with Columbia Pictures' Screen Gems television division. Over the next four decades, the studio produced many successful animated television shows, including Huckleberry Hound, The Flintstones, Yogi Bear, Jonny Quest, Scooby-Doo, and The Smurfs amoung others.

The studio also produced several theatrical films, short subjects, telefims, specials and commercials, earning Hanna-Barbera eight Emmys, a Golden Globe Award, and a star on the Hollywood Walk of Fame, among other merits. In the mid 1980's, the company's fortunes began to decline the profitability of Saturday morning cartoons was eclipsed by weekday afternoon syndication. In late 1991, the company was purchased by Turner Broadcasting System, who used much of the H-B back catalog program its new channel, Cartoon Network. Both Hanna and Barbera went into semi-retirement after Turner purchased the company, continuing to serve as mentors and creative consultants.

During the mid-1990's, Hanna-Barbera began producing original programming for Cartoon Network, including Cartoon Cartoons shows such as Dexter's Laboratory, Johnny Bravo, Cow and Chicken and Powerpuff Girls. In 1996, Turner merged with Time Warner, and Hanna-Barbera became a subsidiary of Warner Bros. Animation. With William Hanna's death in 2001, the studio was absorbed into its parent, and the spinoff Cartoon Network Studios continued the projects of Cartoon Network output. Joseph Barbera continued to work with Warner Bros. Animation until his death in 2006.

Hanna-Barbera Productions currently exists as an in-name-only company used to market properties and  productions associated with the studio's "classic" works such as Yogi Bear, Scooby-Doo and Huckleberry Hound. The Academy of Television Arts & Sciences unveiled a bronze wall sculpture of Hanna and Barbera and their creations in 2005 honouring the duo's work in television and film.
