Gumby
Gumby was started by Art Clokey in 1953. The first 'episode' was a 3-minute short called Gumbasia. It showed moving lumps of clay set to music, and parodied Fantasia. In 1955, Art showed Gumbasia to movie producer Sam Engel, who then paid him for a 15-minute movie called Gumby Goes to the Moon.
