Nickelodeon
The channel began life as a test broadcast on December 1, 1977, as part of QUBE, an early cable television system broadcast locally in Columbus, Ohio. The channel, now named Nickelodeon, launched to a new nationwide audience on April 1, 1979, with Pinwheel as its inaugural program. The network was initially commercial-free and remained without advertising until 1984. Nickelodeon gained a new facelift regarding programming and image that fall, and its ensuing success led to it and its sister networks MTV and VH1 being sold to Viacom in 1985.
Nickelodeon has expanded its franchise through several sister channels and programming blocks. Nick Jr. launched as preschool morning block on January 4, 1988, and was eventually spun-off into a separate channel in 2009. Nicktoons, based on the flagship branding for its original animated series, launched as a standalone channel in 2002.
