Nickelodeon (styled as nickelodeon, commonly referred to as simply Nick, and originally called Pinwheel) 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 children, pre-teens and teenagers 7–16 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 that broadcasts during the interim hours and features reruns of older primetime sitcoms, along with some original series and feature films, and 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.
As of August 2013, Nickelodeon/Nick at Nite is available to approximately 98,799,000 pay television households (86.51% of households with television) in the United States.
