Hanna found the no-notice closing puzzling because Tom and Jerry had been so successful. Television In 1957, Barbera reteamed with his former partner Hanna to produce cartoon films for television and theatrical release. As they had at MGM, the two brought their different skills to the company; Barbera was a skilled gag writer and sketch artist, while Hanna had a gift for timing, story construction, and recruiting top artists. Major business decisions would be made together, though each year the title of president alternated between them. A coin toss determined that Hanna would have precedence in the naming of the new company, first called H-B Enterprises but soon changed to Hanna-Barbera Productions. Barbera and Hanna's MGM colleague George Sidney, the director of Anchors Aweigh, became the third partner and business manager in the company, and arranged a deal for distribution and working capital with Screen Gems, the television division of Columbia Pictures, who took part ownership of the new studio. The first offering from the new company was The Ruff & Reddy Show, a series which detailed the friendship between a dog and cat. Despite a lukewarm response for their first theatrical venture, Loopy De Loop, Hanna-Barbera soon established themselves with two successful television series: The Huckleberry Hound Show and The Yogi Bear Show. A 1960 survey showed that half of the viewers of Huckleberry Hound were adults. This prompted the company to create a new animated series, The Flintstones. A parody of The Honeymooners, the new show followed a typical Stone Age family with home appliances, talking animals, and celebrity guests. With an audience of both children and adults, The Flintstones became the first animated prime-time show to be a hit. Fred Flintstone's signature exclamation "yabba dabba doo" soon entered everyday usage, and the show boosted the studio to the top of the TV cartoon field. The company later produced a futuristic version of The Flintstones, known as The Jetsons. Although both shows reappeared in the 1970s and 1980s, The Flintstones was far more popular. By the late 1960s, Hanna-Barbera Productions was the most successful television animation studio in the business. The Hanna-Barbera studio produced over 3000 animated half-hour television shows. Among the more than 100 cartoon series they produced were The Quick Draw McGraw Show, Top Cat, Jonny Quest, The Magilla Gorilla Show, The Atom Ant/Secret Squirrel Show, Scooby-Doo, Super Friends, and The Smurfs.
