5 years after the launch of the USA network a much-storied animated block of programming took to the airwaves, the USA Cartoon Express. Premiering in 1982, the Cartoon Express was home to some of the most popular syndicated cartoons of the last 30 years. The show was launched as afternoon filler and at first was mostly populated with b-rate material from the Hanna-Barbera library such as Inch High, Private Eye, Dynomutt and Dog Wonder.
