In the U.S., late night programming on Saturday features one prominent sketch comedy show, NBC's "Saturday Night Live", while other stations carry syndicated reruns. Sunday evening is generally treated as a regular weeknight, with popular prime time programs airing. In the United States and Canada, prime time network programs start one hour earlier on Sunday evenings (6:00 or 7:00 p.m., depending on the time zone) than on Monday through Saturdays, an exception to the since-repealed Prime Time Access Rule as part of a 1975 revision that allowed networks to program the time slot on Sundays. No network programming currently airs in the Sunday late night slot.
