A Saturday morning cartoon is the colloquial term for the animated television programming which was typically scheduled on Saturday mornings on the major American television networks from the 1960s to the 1990s. In the United States, the generally accepted times considered to be Saturday mornings are 8 a.m. to noon Eastern. In addition, until the late 1970s, American networks also had a schedule of children's programming on Sunday mornings, though most programs at this time were repeats of Saturday morning shows that were already cancelled, out of production or both. In some markets, some shows were pre-empted in favor of syndicated or local programming.
