CBN is a clear-channel radio station broadcasting at 640 kHz (AM) from St. John's, Newfoundland and Labrador, Canada, and is the local Radio One station of the Canadian Broadcasting Corporation. CBN broadcasts with 10,000 watts, unlike most other clear-channel, Class A stations, which broadcast with 50,000 watts. Per international agreement (NARBA), CBN is grandfathered at 10 kW and Class I-B (later renamed Class A, after the 1981 Rio de Janeiro agreement), whereas the dominant station on this frequency throughout the Americas is KFI Los Angeles, which operates with 50 kW and Class I-A (Class A, after "Rio").
The station was founded in 1932 as VONF, broadcasting on 1195 kilocycles, and was owned and operated by the Dominion Broadcasting Company, a subsidiary of the Avalon Telephone Company (a predecessor of Bell Aliant). In 1934, it merged with a former competitor, VOGY/840, which had also launched in 1932. The VONF call sign was retained.
On March 13, 1939, the Dominion Broadcasting Company was absorbed by the Broadcasting Corporation of Newfoundland, the pre-Confederation public broadcaster, as its first radio station. The frequency was eventually changed to its current 640 AM.

CBN is an Australian television station licensed to, and serving the regions surrounding Orange and Dubbo in central western New South Wales.
CBN-8 Orange commenced broadcasting on 17 March 1962, licensed to Country Broadcasting Services, owners of local radio station 2GZ. They soon changed their name to Country Television Services. CWN-6 Dubbo began transmission on 1 December 1965. Also owned by CTS, they became the first station to completely relay another station's programming, although some station identification, such as test patterns, remained separate.
In 1968, the stations acquired access to the Postmaster-General's microwave link, allowing viewers to see national news programs and other major events live for the first time. By the early 1970s, the stations began' to run into financial difficulties, and it was decided to enter into a joint programming agreement with MTN-9 of Griffith, resulting in the formation of the Television 6-8-9 network (later Mid State Television 6-8-9).
