CFFR is a Canadian AM radio station broadcasting @ 660 kHz in Calgary, Alberta & began broadcasting in 1984. As of April 3 2006, it operates in an All-news Radio format, branded 660 News.
Previously it had operated as oldies station 66 CFR. "CFR" initially stood for "Calgary Family Radio" (with the additional "F" in the call sign being incidental) & later for "Calgary Flames Radio", although game coverage moved to sister station CFAC upon it's relaunch as all-sports.
At the time of the change in format, 66 CFR was capturing an insignificant share of the Calgary listening market with an average of 1% share of hours tuned, contrasting to the #1 station in Calgary in 2006, Country 105, which remained on top of the radio listener's heap with a 13.2% share of hours tuned.
Notwithstanding a number of loyal "oldies" listeners, the change in format was inevitable. The subsequent re-branding is similar to that used by Rogers all-news or news-talk stations in Toronto (680 News), Vancouver (News 1130) & @ least 4 other cities.
