n 1975, Tom and Jerry were reunited with Hanna and Barbera, who produced The Tom and Jerry Show for Saturday mornings. These 48 seven-minute cartoon shorts were paired with Grape Ape and Mumbly cartoons, to create The Tom and Jerry/Grape Ape Show, The Tom and Jerry/Grape Ape/Mumbly Show, and The Tom and Jerry/Mumbly Show, all of which initially ran on ABC Saturday mornings between September 6, 1975, and September 3, 1977. In these cartoons, Tom and Jerry (now with a red bow tie), who had been enemies during their formative years, became nonviolent pals who went on adventures together, as Hanna-Barbera had to meet the stringent rules against violence for children's TV. This format has not been used in newer Tom and Jerry entrees.
