Nickelodeon is an American basic cable children's television channel that originally launched on December 1, 1977 as "Pinwheel", but was relaunched on April 1, 1979 as "Nickelodeon". The channel is owned and operated by Viacom Media Networks, a division of Viacom.

The channel's programming is aimed toward children and adolescents whose ages range between 8-17 years old. However, the weekday morning block (formerly known as Nick Jr. before being revamped as its own channel) contains programming targeted at children ages 2-8. Occasionaly, Nickelodeon will broadcast both original and third party television movies when deemed appropriate. Regular programming runs from Sundays through Wedensdays and Fridays from 7:00 AM to 9:00 PM. Saturday programming lasts from 7:00 AM to 10:00 PM, and Thursday programming lasts from 7:00 AM to 8:00 PM, both Eastern and Pacific Time.

Since July 1985, Nickelodeon has shared space with its sister channel/block, Nick at Nite, which airs more mature programming over the course of the evening and night hours. Nick at Nite is known for reruns of popular primetime sitcoms, such as Full House and George Lopez, alongside occasional original programming and feature films.
