Nippon News Network (NNN) is a Japanese commercial television network owned by Nippon Television (NTV), which itself is controlled by The Yomiuri Shimbun Holdings. The network's responsibility includes the syndication of national television news bulletins to its regional affiliates, and news exchange between the stations.
NNN also operates NTV News24, a 24-hour news channel available on subscription television platforms and also aired on select NNN affiliates during overnights.
Distribution of non-news television programmes is handled by Nippon Television Network System (NNS), another network set up by NTV.
Overview
In the early days of the development of commercial terrestrial broadcasting in Japan, the allocation of broadcast frequencies had a major impact on the selection of core bureaus by broadcasters outside the Kanto Region. Therefore, all commercial broadcasters in the Shikoku Region chose to be part of the Nippon TV network while those in Kyushu Region chose to be part of the Japan News Network. After the launch of Nippon TV in 1953, the broadcaster then aired its first proper news bulletins which includes NNN Today's Events (first aired in 1954), NNN News Flash (first aired in 1956), and Nippon Telenews (first aired 1958).
