Nick at Nite is the evening programming block broadcast over Nickelodeon Sunday - Thursdays from 9 p.m - 6 a.m. and Friday - Saturdays from 10 p.m. - 6 a.m. Eastern and Pacific Standard Time. Nickelodeon is known for its children's shows during the day, while Nick at Nite appeals to adult audiences with a lineup of classic television; largely Viacom-owned syndicated sitcoms, shown with about a ten-year lag. At the choice of Viacom, and despite being aired on the same channel as Nickelodeon, Nick at Nite is treated in the Nielsen Media Research as a separate television network, similar to Adult Swim, a programming block on Cartoon Network and the Jetix block on Toon Disney.
