Answer: Nickelodeon
Nickelodeon (previously known as Pinwheel from 1977 until 1981) is an American cable television channel owned by Viacom. Since the early-1990s and early 2000s, Nickelodeon as a brand has expanded into other territories including Europe, the Middle-East, Russia and Asia. Nickelodeon has been available in Canada since November 2, 2009.
It is often referred to by its shortened name, Nick, a practice that dates back to the early days of the channel. As of 2009, Nick currently has three blocks: Nick at Nite, Nick's Play Date, and the Hollywood Hang. Since 2006, Nickelodeon has been run by MTVN Kids & Family Group president Cyma Zarghami. The channel is aimed mostly at children ages 3–12, with the exception of their prime time block that is aimed at children ages 12–18.
