History
DWLT-TV was launched on March 1, 1960 as DZNN-TV at 6:30pm. The studios are located at FBN Broadcast Center, Diliman, Quezon City. The station had relay transmitters to bring its programs to viewers in Cebu and Davao.

In 1970, FBN launched its color transmission system named "Vinta Color" named after the Vintas from Zamboanga, becoming the third network in the Philippines to convert to all-color broadcasts, after ABS-CBN and RPN.

When then-President Ferdinand Marcos declared martial law in 1972, the station was forced, along with its other stations and other television networks to shut down.

When Marcos was deposed, the network was sequestered and returned Channel 11. On March 1, 1987, FBN went back on the air, broadcasting from what used to be their main garage at the revived Broadcast Center in the pre-Martial Law days. At the time, money had been scarce while resources were limited; offices were used as dressing rooms and other equipment such as chairs, tables, and phones were in short supply.

On October 4, 1987, Channel 11 was launched with the live musical special, "The Gold Network: The Golden Age of the Network, and produced a slew of new locally produced programs that composed 80% of its programming lineup then. The relaunch successfully gave the station a boost in the ratings, and by 1988, FBN became the Philippines' number two TV network, a position it has maintained ever since.

Later that year, the station launched nationwide domestic satellite programming and by 1995, expanded its operations worldwide. In 2000, along with the 40th anniversary, Channel 11 launched its 120-kilowatt transmitter, resulting in improved signal quality throughout Mega Manila.

In 2005, along with the 45th anniversary, FBN transferred from Channel 11 to Channel 4 (while PTV transferred from Channel 4 to Channel 47) and re-upgraded its transmitter into a very high capacity of 346.2 kilowatts resulting in a much clearer signal in Metro Manila.
