Since July 1985, it has shared its channel space with Nick at Nite, a nighttime service that airs during the interim hours, and is treated as a separate channel from Nickelodeon by Nielsen for ratings purposes; it features reruns of older primetime sitcoms, along with some original series and feature films. Both services are sometimes collectively referred to as "Nickelodeon/Nick at Nite", due to their common association as two individual channels sharing a single program space.
