adopt the Smooth AC approach was pioneering smooth-jazz station KTWV in Los Angeles ("The Wave"), under new program director Jhani Kaye. KTWV's transition was successful in improving the station's 25-54 ratings. Other stations followed suit, including the late WLFM-LP in Chicago; WXJZ in Gainesville, Florida; KIFM in San Diego; and WNWV in Cleveland, which relaunched under its former "107-3 The Wave" identity as a Smooth AC on January 4, 2012. However, the Smooth AC format for the most part did not succeed: WLFM, WXJZ and KIFM have switched to other formats, WNWV has evolved back into smooth jazz, and KTWV has continued to progressively downplay (while not entirely eliminating) instrumental music in its shift to a "Smooth R&B" Urban AC format. The Smooth AC format is now virtually extinct on commercial radio. Other former smooth-jazz stations have evolved to Rhythmic Oldies formats while maintaining their previous call letters, notably KOAS in Las Vegas, which saw its ratings in the 25-54 age demographics improve after moving to its "old school" format. KYOT-FM in Phoenix tried the same but has since switched to another format. Non-commercial and AM stations By 2009, as smooth jazz continued its rapid decline on the commercial radio airwaves, a growing number of non-commercial stations (including some LPFMs) have taken up the music and added it to their programming. Among non-commercial stations playing primarily smooth jazz as of June 2016 include: KJZT-LP in Tulsa, Oklahoma; KRWV-LP in Gold Canyon, Arizona; KWBR-LP in St. George, Utah; WNOZ-LP in New Orleans; WAJH in Birmingham, Alabama; WCRX-LP in Columbus, Ohio; WFSK in Nashville, Tennessee; and WBWH-LP in Bluffton, Ohio, which has extended its Sunday-night show "The Chillout Sessions" (featuring a mix of smooth jazz, smooth vocals, and chill music, hosted by Donald Isaac) into its primary format as of October 2011. In addition, some commercial stations which present the format on their HD side channels, such as KKCW in Portland, Oregon, and WDZH in Detroit, do so without or with limited commercial interruption. One of the longest-running non-commercial smooth jazz radio programs in the United States was "The Quiet Storm," which aired weekly on the community-based WGDR in Plainfield, Vermont and its sister station, WGDH in Hardwick, Vermont, both owned by Goddard College. Launched in 1998 and hosted by Skeeter Sanders, "The Quiet Storm" was a 50-50 mix of smooth jazz and soft R&B, presented in "Triple-A" (Album Adult Alternative) style,
