On March 21, 1969, the tower became operational, transmitting television and radio for ABS-CBN and also used to beam color broadcasts in Metro Manila, and to nearby provinces.

After martial law was declared on September 21, 1972, as ABS-CBN suspended their operations the following day, the facility was taken over by the crony-owned BBC-2 from 1973 to 1979; state-run People's Television's predecessors GTV/MBS-4 also occupied the tower from 1974 to 1992 to beam their programs.

When the EDSA Revolution happened, both the tower and Broadcast Plaza were stormed by reformist rebels as escalating battle occurred on February 24, 1986.

Since then, the tower became the primary source of transmission for both DWWX-TV and DWRR and later it began transmitting the company's sister UHF station DWAC-TV in 1996.

[2] On June 30, 2020, the transmitter was shut off due to a cease and desist order from the National Telecommunications Commission after ABS-CBN's legislative franchise expired on May 4, 2020.
