Nick at Nite (stylized as nick@nite) is an American cable and satellite television channel that broadcasts nightly over the channel space of Nickelodeon, which is owned by Viacom Kids & Family Group, division of Viacom. It broadcasts on Sundays through Wednesdays and Fridays from 9:00 p.m. to 7:00 a.m., Thursdays from 8:00 p.m. to 7:00 a.m., and Saturdays from 10:00 p.m. to 7:00 a.m. (Eastern and Pacific Time).
Although it shares channel space with its parent channel, Nielsen counts Nick at Nite as a separate channel from Nickelodeon 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 the same channel space.
Nick at Nite appeals to adult and/or adolescent audiences with a lineup of mainly live-action sitcom reruns and a limited amount of original programming. However, because it shares channel space with Nickelodeon (prefiguring Cartoon Network and Adult Swim), some of Nick at Nite's programming – mainly programs that lead off the lineup each night – is aimed at preteens and adolescents between 8 and 15 years of age. The content on Nick at Nite (though looser in regards to profanity and suggestive dialogue compared to the children's-oriented Nickelodeon) is not as raunchy or violent as content on other primetime networks, encouraging a crossover audience between it and Nickelodeon viewers. Due to its reliance on sitcom reruns whose cable syndication rights are limited to a certain part of the day owing to contracts with studios and/or distributors (for instance, the network holds the exclusive nighttime rights to run Friends, while TBS holds exclusive daytime rights to said series), Nick at Nite's cable provider video on demand service exclusively features only their original series, where available.
Nick at Nite, a network that was originally established as a nighttime cable channel/programming block broadcasting over the channel space of the flagship Nickelodeon channel in the United States, has expanded to include worldwide versions.
Despite the success of Nick at Nite in the United States, most international versions of Nickelodeon do not carry their own Nick at Nite programming block, as those local versions of Nickelodeon outside of the United States either carry children's programming 24 hours a day or run a non-Nick at Nite program block during the nighttime hours. While Nick at Nite's U.S. flagship primarily focuses on reruns of discontinued primetime network sitcoms, some of these international versions have aired reruns of discontinued Nickelodeon series.
In Latin America, Nick at Nite aired every weeknight on Nickelodeon from 10:00pm until 6:00am since February 13, 2006. Since January 2007, shows included: ALF, Mork & Mindy, The Addams Family, The Munsters, Bewitched, I Dream of Jeannie, Growing Pains, The Facts of Life, Diff'rent Strokes, Get Smart and Perfect Strangers, which have been broadcast on other Latin American broadcast and cable channels. It replaced the programming block "Fantabuloso", which aired series aimed at teenagers and was very similar to the U.S. Nickelodeon flagship's now-defunct TEENick block. Until July 4, 2009, the block aired seven nights a week.
