ABS was able to put up its TV tower by July 1953 and import some 300 television sets. The initial test broadcasts began in September of the same year. The very first full-blown broadcast was on October 23, 1953, of a party in Tony Quirino's humble abode. The television station was known as DZAQ-TV. On June 16, 1955, Republic Act No. 1343 signed by President Ramon Magsaysay granted the Manila Chronicle its broadcasting franchise, leading to the formation of the Chronicle Broadcasting Network. The Chronicle Broadcasting Network (CBN) was founded on September 24, 1956 by Eugenio Lopez Sr. and the then-Philippine Vice President Fernando Lopez. The network initially focused only on radio broadcasting. It launched its very own TV station, DZXL-TV 9, on April 19 (or July), 1958. On February 24, 1957, Don Eugenio acquired ABS from Quirino and Lindenberg. A month later, Don Eugenio also acquired Monserrat Broadcasting System. In 1958, the network's new headquarters at Dewey Boulevard were 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 Dewey Boulevard building in Pasay, Rizal. The ABS-CBN brand was first used in 1961. However, it was only on February 1, 1967, that the corporate name was changed to ABS-CBN Broadcasting Corporation. Before it was named ABS-CBN Broadcasting Corporation, the corporate name was Bolinao Electronics Corporation (BEC).
