Z Radio was established in November 2006 as a radio outlet of the University of Baguio. A few years later, it enhanced its programming to serve the public outside the campus. It aired talk programming in the morning and Top 40 format throughout the rest of the day. In 2019, it switched to a mass-based format, with talk programmes from early morning until sign-off.
