Leading the station's first years of broadcast are some of the anchors and reporters transferred from DZRH (one notable example is Rey Langit, who eventually became the station manager in 1991, until he resigned in 2016). The first big news coverage on DWIZ was the country’s annual Independence Day celebrations in 1991, followed immediately by the eruption of Mount Pinatubo. In 1994, DWIZ officially switched to its current 50,000 watt transmitter facility. In 2000, DWIZ relocated their studio from Dominga Building, Pasong Tamo, Makati City (home of Aliw's sister companies BusinessMirror and Pilipino Mirror) to their current home in Citystate Centre in Shaw Boulevard, Pasig. In 2005, DWIZ launched "Karambola", a morning political commentary program featuring a panel of journalists and columnists led by Jonathan De la Cruz. "Karambola" is now one of the station's longest-running programs. On January 3, 2014, DWIZ signed a 3-year memorandum of agreement with Radio Philippines Network (owner of CNN Philippines-affiliated stations and Radyo Ronda) for the expanded coverage of the both TV and radio networks nationwide.
