CHBN signed on the air as 91.7 The Bounce on February 17, 2005. When the station first signed on, the station aired a rhythmic top 40 format, but moved to the current CHR format in December 2005. They became the only CHR station in the Edmonton market when CKRA shifted their format to play a Hot AC format in August 2005, and then later to country music four months later. After this surprise development, The Bounce shifted to more mainstream pop music. Every year in October, in an event called "Bras Across the Bridge", for Breast Cancer Awareness Month, CHBN collects bras from listeners, donating $1 to the Canadian Breast Cancer Foundation for every bra collected. At the end of the month, they then tie all the bras together and span the string of bras across the High Level Bridge as many times as they can. At the time of their launch, CHBN was jointly owned by CHUM Limited and Milestone Radio. In June 2007, all of CHUM's assets, including its share of CHBN, were sold to CTVglobemedia. On June 23, 2010, it was announced that CHBN would be sold to Rogers, along with its sister station in London, Ontario, CHST-FM, pending CRTC approval. The acquisition also saw the reunion of CHBN with its sister station CKEM-DTfor the first timesince 2007. When CFMG-FM flipped from AC to CHR as Virgin Radio, it marked the first three-station FM top 40 battle in Edmonton as of February 2011. Since the launch of Virgin Radio, The Bounce has been playing fewer commercials, as seen with the introduction of Commercial Free Mondays, and playing more currents and higher-charting songs than its competition. CHBN will continue to report on Mediabase and Nielsen BDS' Canadian contemporary hit radio panel. On February 24, 2017, at 10 a.m., CHBN re-branded as Kiss 91.7, adopting the KiSS brand used by other Rogers CHR and hot AC stations and launching with a 91-hour commercial-free marathon.
