Sealab 2020

The series took place in the year 2020 at Sealab, an underwater research base on the Challenger seamount.

Sealab 2020 marked Hanna-Barbera's first return to the action-adventure genre since increased political and social pressures saw that by 1972, most action programming had been removed from the Saturday-morning slot, following pressure from parents' lobbying groups such as the Action for Children's Television (ACT). Alex Toth, who had provided work on prior Hanna-Barbera series such as Space Ghost, returned to the studio and designed all aspects of the series including vehicle and character designs. While Toth enjoyed the creative and artistic freedom granted to him in developing and designing the show, he felt the frugal animation Hanna-Barbera was known for hampered the ability to portray a convincing underwater environment. ==Broadcast==

Sealab 2020 premiered on Saturday September 9, 1972 on NBC during the 11:00-11:30AM timeslot. As NBC's orders were characterized by 13 episode batches to run 4 times over the year in order to cover the 52 week television schedule, the series ran on NBC until September 1, 1973 at which point it was dropped from the 1973–74 Saturday morning schedule. The series was rebroadcast on Cartoon Network from December 6, 1992 to March 14, 1993 as part of Cartoon Network's Boomerang programming block dedicated to showcases of older cartoons. ==Merchandise==

In 1973, a board game based on the show was produced by Milton Bradley. ==Parody follow-up==
