An online radio station.

On November 4, 1989, KB eventually was reformatted into 89 DMZ as an all-dance radio station that featured non-stop dance music launched in November 18, 1989.

The first 89 DMZ era: 1989-February 28, 2001

In November 18, 1989, the station reformatted and changed its callsign to DZMZ-FM and rebranded as 89 DMZ (Danze Music Zone), which played dance music such as disco, new wave, euro/Italo disco, electronic dance music, house and eurodance, hip hop, R&B, pop, OPM, hot AC and remixed music from the 1970s, 1980s and 1990s. The station is a brainchild of Bingo Lacson, the radio station manager of IBC as the big boss and the DJs like Peewee, Chinaman, The Unbeatable, The Mouth, The Shadow and The Bug. The late rapper, Francis Magalona, worked with the station through his program The Word-Up Show, which aired on Saturday nights. It also became the home of the Mobile Circuit every Friday night. Back then, the station was operated 18 hours a day, from 6 am to 12 mn. Since then, 89 DMZ became famous as The Nation's #1 Danze Music Station as the original slogan.
