Mighty Mouse was not extraordinarily popular in
theatrical animation, but was still
Terrytoons' most popular character. What made him a cultural icon was television. Most of the short film studios, both live-action and animated, were in decline by the 1950s, pressured both by the loss of film audiences to television as well as the increased popularity (and financial benefits) of low-budget, stylized,
limited animation. Most of the studios cashed out of the short-film production business and began licensing or selling their back catalogs to television.
Paul Terry went as far as to sell the entire Terrytoon company to
CBS in 1955. The network began running
Mighty Mouse Playhouse in December 1955. It remained on the air for nearly twelve years (and featured
The Mighty Heroes during the final season). Mighty Mouse cartoons became a staple of children's television programming for a period of over thirty years, from the 1950s through the 1980s. ==End of the Mighty Mouse film series==
