GMA Network was founded by Robert La Rue Stewart in 1950 as Republic Broadcasting System (RBS) with flagship AM radio station DZBB. RBS ventured into television in 1961 and began broadcasting on Channel 7 in the Greater Manila Area.
In 1974, the triumvirate of Felipe L. Gozon, Menardo R. Jimenez and Gilberto M. Duavit took over the management of RBS. In 1996, RBS was renamed GMA Network, Inc.
Today, GMA Network, Inc. is the leading broadcasting company in the Philippines which produces the most innovative, most trusted, and top rating TV programs. It operates a network of 47 VHF and 41 UHF TV stations, as well as 24 radio stations throughout the country.
Apart from its television and radio businesses, GMA also owns a wide array of media-related entities engaged in program syndication, film production, music publishing and distribution, set design and implementation, audio-visual production, and new media.
GMA Network, Inc. was officially listed in the Philippine Stock Exchange in 2007.
