CKCK-FM

Owned by Rawlco Communications, it broadcasts an adult hits format branded as Jack 94.5.

CKCK's studios and offices are located at 2401 Saskatchewan Drive in Regina, along with sister stations CJME and CIZL-FM.

Around the same time, the station conducted the British Empire's first live remote broadcast of a church service.

The 1960s saw CKCK at its commercial peak, dominating the broadcast market in Regina and southeast Saskatchewan.

But its massive market share started to erode in the early 1960s as rival CJME came under the ownership of the Rawlinson family, forerunner of Rawlco Communications, and switched from a "beautiful music" format to Top 40 rock music.

Another rival, CKRM, switched from a middle-of-the-road (MOR) format to country music in 1971 and CBC Radio belatedly began building up CBK's local news and current affairs staff.

It lost further ground when CKRM increased its sports programming, notably winning the rights to the CFL's Saskatchewan Roughriders.
