Nickelodeon (often simply called Nick and originally called The Pinwheel Network) is an American basic cable and satellite television network that is owned by the MTV Networks Kids & Family Group, a unit of the Viacom Media Networks division of Viacom. Aimed mainly at pre-teens and teenagers 11–16 years of age and its preschooler-targeted shows aimed at children 2–6, it broadcasts on Sunday-Wednesdays from 7 a.m.-8 p.m., Thursdays and Fridays from 7 a.m.-9 p.m. and Saturdays from 7 a.m.-10 p.m. (Eastern and Pacific Time).
Since 1985, it has shared its channel space with Nick at Nite, a nighttime service broadcasting during the interim hours that features reruns of older primetime sitcoms, along with some original series and feature films, which is treated as a separate channel from Nickelodeon by A.C. Nielsen Co. for ratings purposes. Both services are sometimes collectively referred to as "Nickelodeon/Nick at Nite", due to their common association as two individual channels sharing a single channel space. Since 2006, Nickelodeon has been run by president and chief executive officer Cyma Zarghami.
Nickelodeon's schedule currently consists largely of original series aimed at pre-teens and young teenagers, including animated series (such as SpongeBob SquarePants, The Fairly OddParents, The Penguins of Madagascar, Teenage Mutant Ninja Turtles and Sanjay and Craig), to live-action comedy and action series (such as Marvin Marvin, Power Rangers Megaforce, Supah Ninjas and Sam & Cat), as well as series aimed at preschoolers (such as Team Umizoomi, Peter Rabbit and Dora the Explorer). The channel also airs repeats of now-defunct Nickelodeon original series (such as Victorious, Drake & Josh, and iCarly), acquired shows (such as Rocket Monkeys, Winx Club, sister channel Nicktoons series NFL Rush Zone: Season of the Guardians and The Adventures of BD) as well as occasional original made-for-TV movies. The channel also airs bi-monthly special editions of Nick News, a newsmagazine series aimed at children that debuted in 1992 as a weekly series.
