Nickelodeon was a Japanese television channel which targeted children, teens and adults. It is the brand of Viacom Networks Japan K.K. (a subsidiary of Viacom Media Networks division of Viacom). Started on November 1998 as a cable and satellite television channel, Viacom attempted to bring their Nickelodeon brand to the Japanese market. However, due to declining viewership, the television channel was taken off the air on September 30, 2009. After the channel's closure, some programs were moved to other specialty channels (including MTV Japan), DTH satellite channels and terrestrial television networks. New programs made their national television premiere on other channels: For example, The Penguins of Madagascar made debut on NHK Educational Television on April 4, 2010. The official website is still online, with program information, website games and downloadable stuffs.
In October 2017, Viacom brought back into the brand in Japan starting on January 30, 2018. It is currently available exclusively on dTV-Channel (a subscription TV streaming service of NTT Docomo) and Hulu Japan.
