CHOZ-FM is a Canadian radio station based in St. John's, Newfoundland and Labrador. Its main St. John's transmitter broadcasts at 94.7 MHz, with additional transmitters located throughout the island. The station, known as OZFM, is one of the various media properties of the Stirling family; this includes local television station CJON-DT. History CHOZ launched on June 15, 1977 at 93.9 FM, soon after Geoff Stirling sold his interest in what is now CJYQ. It was originally a full-time rock station known as Radio OZ, The Rock Of The Rock. It eventually transitioned into a CHR/Classic Rock hybrid fusion type format under the OZFM brand; nonetheless it kept "The Rock Of The Rock" slogan. On August 1, 1984, CHOZ was approved to move to 94.7 FM. The station's success was driven largely by the strength of its morning show, The Dawn Patrol, hosted by Randy Snow, Deborah Birmingham and Larry Jay. In the summer of 2003, Snow left the Dawn Patrol to join CKIX-FM to host his own morning show. His replacement was Brian O'Connell, who left the VOCM to join CHOZ. By 2004, CHOZ began shifting towards hot adult contemporary, with slogans like "More Music, More Variety" and "Newfoundland's #1 FM Station". In April 2007, O'Connell took over as station manager for the OZFM Network and host of the daily Electric Lunch program. Then, O'Connell left CHOZ and now works with Stingray Radio. Paul Kinsman was O'Connell's on air replacement, joining longtime Dawn Patrol veterans Birmingham and Jay. On August 17, 2009, CHOZ changed its format to active rock. On January 2, 2012, CHOZ flipped back to hot AC, with a new slogan "Today's Best Music". This ended the use of their longtime slogan "The Rock of the Rock". The station also resurrected their longtime heart-rainbow logo that was used from the late 1980s to 2007. The following month, the station surfaced on the Mediabase Canadian hot AC panel. In August 2012, Kinsman and Jay left the Dawn Patrol, which was renamed The Morning Rush and featured a new host, Robert Shawn, alongside the only remaining original host Birmingham. In January 2013, the pair were joined by their former behind the scenes producer, Laura Woodworth. Birmingham left the station in January 2014 and her replacement on the Morning Rush was Stephanie O'Brien, previously with VOCM-FM. Woodworth left the station in November 2014. In July 2015, Shawn switched shifts with Stephen
