Smooth jazz is a musical style that grew out of jazz fusion and is heavily influenced by R&B, funk, rock, blues and pop music styles (separately, or, in any combination). Modern derivatives of the genre include the more-recent New Adult Contemporary format of broadcast radio. "Smooth jazz" has been successful as a radio format; however, in 2007, the popularity of the format began to slide. Consequently, it was abandoned by several high-profile radio stations across the U.S.A., perhaps most notably by WQCD (Now WRXP) in New York and KKSF in San Francisco. Many industry insiders have speculated that the smooth jazz format may die out, particularly with many of industry giant Clear Channel Communications' stations dropping the genre. However, smooth jazz concerts, recording sales—as well as increased smooth jazz offerings on the Internet—continue to show strong fan support for the genre.
