Radio Stations, Broadcasting Stations & Web Radio

Early radio was actually a radio telegraph systems which did not carry audio. On Christmas Eve in 1906, Reginald Fessendenn made supposedly the first audio transmission that could be considered a broadcast.  Charles Herrold started broadcasting in California in 1909 and was carrying audio by the next year.

During the next ten years, many radio enthusiast had build their own radio receivers. Westinghouse, who owned  KDKA AM of Pittsburgh, Pennsylvania started broadcasting as the first licensed "commercial" radio station on November 2, 1920 as the results of the US presidential election in 1920. Broadcasting in the same year, on May 20, 1920, without a license was the Montreal station, now CFCF-AM, and on August 20, 1920, the Detroit station, now WWJ.

On August 27, 1920, Radio Argentina began regularly scheduled transmissions from the Teatro Coliseo in Buenos Aires making its own priority claim. The station was licensed on November 19, 1923. The delay was due to the lack of official Argentine licensing procedures before that date. This station continued regular broadcasting of entertainment and cultural fare for several decades.

Internet based radio became feasible in the mid '90s, and the new medium required no licensing with stations broadcasting from anywhere in the world without the need for "over the air" transmitters, and in 1996, 'A' Net Station (A.N.E.T.) began broadcasting commercial free from Antarctica.
 

A Radio network (US) is an broadcasting entity that provides programs to individual Radio stations, which are only licensed to broadcast in a specific area. Each network can hold a few stations it owns and operates, usually in the big markets.
