GMA Network (an acronym of its legal name, Global Media Arts and commonly known as GMA) is a Philippine commercial broadcast network, serving as the flagship property of publicly traded GMA Network Inc.. The network is headquartered in the GMA Network Center in Quezon City and its transmitter facilities, Tower of Power, are located at Tandang Sora Avenue, Barangay Culiat also in Quezon City, with regional stations and offices located in over twelve major cities across the country including Dagupan, Bacolod, Iloilo, Cebu and Davao. GMA Network (formerly known as Republic Broadcasting System, GMA Radio-Television Arts and GMA Rainbow Satellite Network) is commonly referred to as the Kapuso Network in reference to the outline of the company's logo; the branding was introduced on October 27, 2002, during an episode of its now-defunct Sunday noontime variety show, SOP.
The original meaning of the GMA acronym was Greater Manila Area, referring to the initial coverage area of the station. As the network expanded, it changed into Global Media Arts. GMA Network is one of the largest television and media network in the Philippines. GMA's first broadcast on television was on October 29, 1961, as Republic Broadcasting System (RBS) on DZBB Channel 7, almost a decade after the success of its radio station DZBB. It is the first television network in the Philippines to formally launch in anamorphic widescreen format.
