Soon after the first World War in 1933, on May 8, 1933, the U.S. government established and operated radio station DZFM (then KZFM) in the Philippines on frequency 710 kHz with a power of 10,000 watts through the United States Information Service. In September 1946, two months after the Philippines became an independent country from the U.S.A., KZFM was turned over to the Philippine government. With the transfer was born the Philippine Broadcasting Service, PBS the second broadcasting organization after Manila Broadcasting Company.
