Weekends have a slightly different setup than weekdays. On Saturdays, morning shows share time with the saturday-morning cartoon, where the networks usually fulfill federally mandated regulations requiring the airing of educational or children's shows (such as regulations on children's television programming in the United States, where at least three hours of this programming must air weekly across all television stations; although most of the children's programs have increasingly become more live action in nature than animated). Sunday mornings, often known as a graveyard slot (particularly very early on Sunday morning) feature more morning shows, public affairs designed for very small audiences, additional infomercials, religious broadcasting, and a series of influential political and news analysis/interview programs known as the Sunday morning talk show.
