1970s

The 1970s were the third decade since William Hanna and Joseph Barbera founded Hanna-Barbera.

Following the success of Scooby-Doo, Where Are You!, the company produced several spin-offs for the series, such as The New Scooby-Doo Movies (1972) and The Scooby-Doo Show (1976), which were regularly continued to be produced by Hanna-Barbera into the 1990s.

For the majoraty of the decade, the studio produced nearly two-thirds of all Saturday morning cartoons in a year, which further bolstered their reputation as "The General Motors of animation". Many H-B series produced at the time, including Josie and the Pussycats, The Funky Phantom, Speed Buggy, Jabberjaw, and Captain Caveman and the Teen Angels were built upon the mystery template from Scooby-Doo, with many focusing on the adventures of teenagers solving mysteries with a comic relief of sort. The studio also produced cartoons outside of the mystery genre, with series such as Hong Kong Phooey, The Great Grape Ape Show, and The Mumbly Cartoon Show.

They also attempted to follow the success of their Flintstones series, which included the spin-offs The Pebbles and Bamm-Bamm Show and The Flintstone Comedy Hour, and other series such as The Roman Holidays, Where's Huddles? and Wait Till Your Father Gets Home; the last two of which were their first prime-time sitcom since The Jetsons.

In 1973, Hanna-Barbera adapted DC Comics' Justice League of America for the Super Friends action-adventure series, which spawned several iterations through 1986.

Charlotte's Web, adapted from the E.B. White novel and Hanna-Barbera's first film not based on their shows, was distributed by Paramount Pictures in 1973.
