After MGM shut down its animation studio in 1957, H-B Enterprises became Hanna and Barbera's full-time job, and the company was re-named Hanna-Barbera Productions in 1960. Over the next three decades, Hanna-Barbera Productions produced many successful cartoon shows, including The Huckleberry Hound Show, The Flintstones, Top Cat, The Yogi Bear Show, The Jetsons, Jonny Quest, Scooby-Doo, and The Smurfs, many of which would go on to become icons of Western pop culture. In the mid-1980s, the company's fortunes declined somewhat after the profitability of Saturday morning cartoons were eclipsed by weekday afternoon syndication.
