core playlist of Jazz FM. Although from the start Jazz FM played jazz, soul and softer R&B were added to appeal to the 25-45-year-old market. This was especially true after GMG Radio took over the running of the station and in November 2004 after an agreement with Ofcom, when jazz was dropped from the daytime playlists. John Simon, GMG programme director, said that the station was never licensed as a jazz station, but as a station that played a broad range of black music styles. Ofcom licensing requirements As part of its licence agreement with Jazz FM, Ofcom stated that Jazz FM had to dedicate at least 50% of the daytime output before 19:00 to jazz, and that the music "must sit well with the label jazz". However, from 15 November 2004, as part of an agreement with GMG, Ofcom agreed to allow GMG to change the format, with the 50% jazz in daytime requirement dropped. John Myers said, "The policy we are going on is ratings by day, reputation by night. Jazz is much more of a night-time listen so the changes fit well." As a result, jazz was increased from 40 to 45 hours and the Dinner Jazz programme hours were increased from two to three. Criticism Since the station began in 1990, fans of traditional and modern jazz criticised Jazz FM for playing more 'accessible' music, such as smooth jazz, British jazz and blues singer George Melly stated to The Independent in 2003 that he had become so disillusioned with Jazz FM's playlist he had stopped listening to the station, describing the music as "middle of the road". Grammy Award-winning jazz musician John Chilton stated that Jazz FM was failing to reach its remit for jazz and that he would prefer the station adopt a jazz-only policy. In a 2006 article for theJazz, musician Digby Fairweather said Jazz FM had turned into a "tragic and swift disaster story" and that the change of playlist was "responsible for both the attempted rape and (fortunately abortive) re-definition of the music" to which no-one within the Jazz FM coverage area would forgive. Radio Authority Investigation In March 2003 the Radio Authority (embodied into Ofcom, the UK government's communications regulator) investigated Jazz FM after it received two complaints from listeners that the station was playing more pop music after changes to the playlist in January 2003.
