Animation in the United States in the television era

The television era of American animation was a period in the history of American animation that gradually started in the late 1950s with the decline of theatrical animated shorts and the popularization of television animation, reached its peak during the 1970s, and ended around the mid-1980s. This era was characterized by low budgets, limited animation, an emphasis on television over the theater, and the general perception of cartoons being primarily for children.
