Saturday-morning cartoon

"Saturday-morning cartoon" is a colloquial term for the original animated series and live-action programming that was typically scheduled on Saturday and Sunday mornings in the United States on the "Big Three" television networks. The genre's popularity had a broad peak from the mid-1960s through the mid-2000s; over time it declined, in the face of changing cultural norms, increased competition from formats available at all times, and heavier media regulations.^[1][2][3] In the final two decades of the genre's existence, Saturday-morning and Sunday-morning cartoons were primarily created and aired to meet regulations on children's television programming in the United States, or E/I. Minor television networks, in addition to the non-commercial PBS in some markets, continue to air animated programming on Saturday and Sunday while partially meeting those mandates.^[4][5]

In the United States, the generally accepted times for these and other children's programmes to air on Saturday mornings were from 8:00 a.m. to approximately 1:00 p.m. Eastern Time Zone. Until the late 1970s, American networks also had a schedule of children's programming on Sunday mornings, though most programmes at this time were repeats of Saturday-morning shows that were already out of production.^[6][7] In some markets, some shows were pre-empted in favor of syndicated or other types of local programming.^[8]
