Overview
LCN assignments of JNN affiliates

Radio Tokyo (KRT, Tokyo Broadcasting; now TBS Holdings) was formed on 1 August 1959 as Japan's first television news network to compete with the Japan Broadcasting Corporation (NHK). The network relay station of the special programme for the wedding of Crown Prince Akihito (later the 125th Emperor, now Emperor Emeritus), which was broadcast on that year, became a member almost as it was. At that time, the Ministry of Posts and Telecommunications (currently the Ministry of Internal Affairs and Communications) assumed that NHK was the only national television broadcaster, and that private broadcasters were local broadcasters within each prefecture. However, unlike radio, in the case of television, in order to broadcast national news that could compete with NHK, it was necessary to exchange news video materials between each station.

Prior to this, "Tokyo Telenews" produced by Radio Tokyo was broadcast nationwide by 16 initial member stations. Among them, Hokkaido Broadcasting (HBC), Chubu Nippon Broadcasting (CBC, now: CBC Television), Osaka Television Broadcasting (OTV, the predecessor of Asahi Broadcasting Television), Radio Kyushu (RKB, the predecessor of RKB Mainichi Broadcasting) and Radio Tokyo in the previous year. The five stations formed an exclusivity pact.

At the time of JNN's inauguration, other stations were also broadcasting national news programs that exchanged materials between broadcasting stations, but Nippon Television distributed news produced by itself to networked stations, Fuji Television and Nippon Educational Television (NET TV, currently TV Asahi) was broadcasting nationwide in the form of purchasing and distributing news programs produced by news program production companies. Especially in the case of NET, the Asahi Shimbun was involved in the production. On the other hand, JNN does not have a relationship with a specific newspaper company, it is an independent production and a joint production of member companies. It was different from other series in that it was just a position of representative.

In the early days, each station was free to replace the title of the news program, but on March 31, 1975, after the affiliation change in Kansai from Asahi Broadcasting TV to Mainichi Broadcasting, all network member stations were unified.

It consists of 28 full-time stations. There are no JNN member stations in Akita, Fukui, Tokushima, and Saga prefectures.

In principle, the color of the logo mark is green and displayed as JNN (on the official website), but since October 2017, the regular news logo has been changed to its own, and "New Information 7days Newscaster" etc. also use their own logos. In addition, the “JNN” logo of “TBS (affiliated station abbreviation) NEWS DIG Powered by JNN”, which began distribution in April 2022, is also unique. In addition, no program distribution station telop has been issued.

Features

As a whole, there are many long-established stations that also operate AM radio, and most of the JNN affiliated stations that have "broadcasting" (放送, Hōsō) in the name are the first commercial television stations (first station) in the area. All first stations in Hokkaido, Tohoku (Pacific side), Shizuoka prefecture, Nagano prefecture, Niigata prefecture, Ishikawa prefecture, Kinki region, Chugoku region (excluding Yamaguchi prefecture), Kyushu/Okinawa region are also members of the Japan Radio Network (JRN). Therefore, if the basic station is virtually included, it is all concurrently operated as radio and TV (Sapporo and Fukuoka are originally concurrently operating radio and TV by the same corporation, Tokyo, Nagoya, and Osaka are effectively concurrently operating radio and TV by the same broadcasting holding company), and at the same time are also the main stations of JRN.

In digital broadcasting, all affiliated stations display their own logo in the upper right corner of the screen during broadcasting, excluding commercials, from the viewpoint of video rights protection (some affiliated stations do not do so with 1seg). Currently, the five major networks implement it on all stations, but only JNN has been doing it since the beginning of broadcasting.

Member stations distribute G-Guide program data (host station of EPG G-guide).
