Nation Broadcasting Corporation (NBC) is a Philippine radio and television Broadcast company established in 1963. As of December 2013, NBC is a subsidiary of MediaQuest Holdings, Inc. under the PLDT Beneficial Trust Fund. NBC operates primarily involved in radio and television broadcasting with affiliate by sister network TV5 Network, Inc. and its corporate offices and studios are located at the TV5 Media Center, Reliance cor. Sheridan Sts., Mandaluyong, Metro Manila, Philippines. History Radio NBC was established by Abelardo Yabut, Sr. in 1963, coinciding with the launch of DXYZ, the network's pioneer AM station in Zamboanga City, using a surplus transmitter that he bought from Deeco Electronics in Manila. Throughout the next years, NBC established a string of 10 AM stations in provincial areas. In 1973, Yabut put up DWFM 92.3 in Manila, his first entry to the nation's capital, and the third FM station in the said area. Two years later, in 1975, NBC put up the first FM station in Cebu City, DYNC 101.9; and DXFM 101.9 in Davao City. In 1987, NBC acquired DWXX 1026 AM from Hypersonic Broadcasting Center and it was reformatted as DZAR, which featured news, commentaries, and well-balanced mix of entertainment and music programming. In 1998, DZAM changed its call letters to DZAR, and reformatted into a news and talk based station. NBC also pioneered in many ways as the first network to broadcast 24 hours a day outside of Metro Manila (via DYCB 765 in Cebu City). It was the first network to bridge the archipelago with the utilization of satellite broadcasting, and continues to cover the live games of the Philippine Amateur Basketball League and the Philippine Basketball Association (the latter broadcasts this time via the Radyo5 News FM Network). In 1996, NBC has grown to become a nationwide network of AM & FM stations: 16 AM stations and 15 FM stations in 20 cities. In 1998, NBC became the only FM radio network in the Philippines consisting of member-stations named after their respective markets. DZAR was the first to launch in 1998 through its nationwide transmission. At that time, DZAR 1026 and other NBC AM stations were rebranded as Angel Radyo. In 2005, The Kingdom of Jesus Christ (KJC) leader Pastor Apollo C. Quiboloy and the Swara Sug Media Corporation acquired all NBC AM stations and rebranded it as Sonshine Radio. In 1973, DWFM was established as the first FM station
