Nick at Nite (stylized as nick@nite) is an American night time programming block broadcast by the American basic cable channel Nickelodeon. It typically broadcasts Monday to Thursday nights from 9 p.m. to 6:30 a.m. ET/PT, Friday and Saturday nights from 9 p.m. - 6 a.m. ET/PT, and Sunday nights from 8 p.m. to 6:30 a.m. ET/PT. The block is similar to Adult Swim, the programming block that shares channel space with Nickelodeon's rival Cartoon Network. Nick at Nite is primarily marketed towards adults, mainly carrying syndicated sitcoms and films from as recent as the mid-1990s to the 2010s. Paramount Media Networks generally regards the block as a separate network timesharing with Nickelodeon on the channel, in a fashion similar to how Warner Bros. Discovery Networks treats Cartoon Network and Adult Swim. Via Nickelodeon, Nick at Nite is available in 92.0 million households in North America as of January 2016. In 1984, after the Hearst Corporation, NBC, and ABC announced their plans to spin off A&E into a separate 24-hour cable channel, Nickelodeon's general manager, Geraldine Laybourne, was asked by MTV Networks President Bob Pittman to develop programming for the vacated timeslot. This was to take advantage of valuable satellite time, as A&E was moving to its own channel. Laybourne sought the help of programming and branding consultants Alan Goodman and Fred Seibert of Fred/Alan Inc. – who were previously successful in branding MTV and Nickelodeon's extensive 1984 rebranding – to come up with new programming ideas. The transition to a 24-hour broadcast for Nickelodeon took place in June, with some cable providers substituting the primetime schedule of other niche-interest networks onto the channel space. After being presented with over 200 episodes of The Donna Reed Show (a 1950s sitcom which Laybourne despised), Goodman and Seibert conceived the idea of the "first oldies TV network." They modeled the new evening and overnight programming block on the successful oldies radio format, "The Greatest Hits of All Time," and branded the block with their next evolution of MTV- and Nickelodeon-style imagery and bumpers.
