GMA Network, Inc. is the leading free-to-air media broadcasting company in the Philippines. It is principally engaged in television and radio broadcasting, production of television programs for domestic and international audiences and other related businesses. The company (then known as Loreto F. de Hemedes, Inc.) started operating its radio station DZBB in 1950 through Robert Stewart, an American war correspondent, known to many as “Uncle Bob.” Eleven years later, on October 29, 1961, the company ventured into television and started operating TV Channel 7. In May 28, 1974, the company changed its name to Republic Broadcasting System, Inc. In the same year, Gilberto M. Duavit, Menardo R. Jimenez and Felipe L. Gozon took over the management of the station.
