Children's television is nearly as old as television itself, with early examples including shows such as Play SchoolCaptain TuggThe Magic RoundaboutHowdy DoodyThe MuppetsIvor the EngineClangersNoggin the NogFlower Pot MenCaptain KangarooSesame StreetThe Electric Company, and Mister Rogers' Neighborhood. In the United States, early children's television was often a marketing branch of a larger corporate product, such as Disney, and it rarely contained any educational elements (for instance, The Magic Clown, a popular early children's program, was primarily an advertisement for Bonomo's Turkish taffy product). This practice continued, albeit in a much toned-down manner, through the 1980s in the United States, when the Federal Communications Commission prohibited tie-in advertising on broadcast television (it does not apply to cable, which is out of the reach of the FCC's content regulations). Though there is some debate on the intended audience, later non-educational children's television programs included the science fictionprogrammes of Irwin Allen (most notably Lost in Space[citation needed]), the fantasy series of Sid and Marty Krofft, the extensive cartoon empire of Hanna-Barbera and the numerous sitcoms that aired as part of TGIF in the 1990s.
