It is Western Canada's oldest and one of the most-listened-to commercial FM stations in Vancouver along with sister station CFBT-FM.
This was most likely caused by the launch of Rhythmic Top 40 (now Mainstream Top 40) station CFBT-FM in 2002 and took away the majority of the station's younger audiences, which prompted CKZZ to seek an older audience that listened to the station in its 90's heyday.
On July 2013, iHeartRadio began adding stations from outside the United States like CHUM-FM and CFBT-FM in Canada and Virgin Radio Dubai in the United Arab Emirates.
