The 1980s also saw a number of cartoons based on children's toys, such as "Teenage Mutant Ninja Turtles", ', "The Transformers", "My Little Pony 'n Friends", "He-Man and the Masters of the Universe", ', "Jem and the Holograms", "ThunderCats", and "Care Bears". There were even cartoons based on "Pac-Man" video games and "the Rubik's Cube". Some of them even inspired feature films. While many of them were successful with children, shows like these were accused of being glorified toy commercials by parents' groups such as Action for Children's Television. These groups also objected to the level of violence in many of these shows. ACT's efforts to curb these trends resulted in the Children's Television Act, enacted in 1990 and strictly enforced by the FCC starting in 1996.
