Users are able to upload and view video content, however niconico was unique at the time in that user comments would be overlaid directly onto the video synced to a specific playback time. The staff at the time decided that instead of going with a cool, flashy name, it would be better to go with a name with a friendly feel, as this might possibly help them win popular opinion and avoid issues further down the line. Before niconico was formed, there were concerns in regards to copyright and the legality of the service. “Niconico” is a Japanese ideophone, meaning to smile.
Niconico (formerly Nico Nico Douga, abbreviated as NND) is Japan's largest video sharing service provided by Dwango.
