Nickelodeon (Nick for short) is a cable TV network primarily for children and pre-teens, but also features shows for teenagers in TEENick. The first Nickelodeon channel was American, but there are now several channels in different countries such as Japan, Australia, and UK.
Nickelodeon has produced and aired many programs. The channel became known for its iconic green slime, originally used on the Canadian sketch-comedy show You Can't Do That on Television. It was then adopted by the station as a primary feature of many of its shows, especially Slime Time Live, U-Pick Live, and Friday Night Slimetime.
Many adults know the service best for its Nick at Nite offerings of classic TV sitcoms in the prime-time and overnight hours.
