The Nippon News Network (NNN) and Nippon Television Network System (NNS) are Japanese commercial television networks organised by Nippon Television (NTV) in Tokyo, which is owned by The Yomiuri Shimbun Holdings. NNN provides national news and current affairs programming to its regional affiliates, while NNS feeds entertainment and other non-news programmes. NNN and NNS are made up of 30 affiliates, including three stations that are double- or triple-affiliated with rival networks.
NNN was founded on 1 April 1966, while NNS was founded on 14 June 1972.
