The nucleus of ABS-CBN Corporation began in 1946 with Bolinao Electronics Corporation (BEC). BEC was established by James Lindenberg, now dubbed as the father of Philippine television, an American electronics engineer who went into radio equipment assembly and radio broadcasting. At that time, the largest media company was Manila Broadcasting, with DZRHas the leading radio station. In 1949, James Lindenberg shifted Bolinao to radio broadcasting with DZBC and mastermindedthe introduction of television to the country in 1953. In 1951, Lindenberg partnered with Antonio Quirino, brother of then Philippine President Elpidio Quirino, in order to try their hand at television broadcasting. In 1952, BEC was renamed as Alto Broadcasting System or ABS. "Alto" was a contraction of Quirino’s and his wife’s first names, Tony and Aleli. Though they had little money and resources, ABS was able to put up its TV tower by July 1953 and import 300 television sets. The initial test broadcasts began on September of the same year. The very first full-blown broadcast, however, was on 23 October 1953, of a party in Tony Quirino's home. The television station was known as DZAQ-TV.

In 1958 the network's new headquarters at Roxas Boulevard was inaugurated, and all radio and television operations were consolidated into its two buildings, the radio stations at the Chronicle Building at Aduana Street, Intramuros, Manila, and the TV operations at the brand new Roxas Boulevard building in Pasay City In the late 1950s, Don Eugenio's son, Geny Lopez saw the potential of TV to reach and link Filipinos across the archipelago.
