Beginnings

The nucleus of what ABS-CBN would be began in 1946 with Bolinao Electronics Corporation (BEC). BEC was put up by James Lindenberg, an ex-GI and electronics engineer who went into radio equipment assembly and radio broadcasting. At that time, the giant Philippine network was Manila Broadcasting, with DZRH as the top station.

In the 1951, Lindenberg partnered with Antonio Quirino, brother of then President 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 October 23, 1953, of a party in Tony Quirino's home. The broadcasting channel was known as DZAQ-TV Channel 3.
