It was a ground-breaking station in the days when the format was often called “New Age/Jazz” or “New AC.” But it hasn’t shown as strongly in the Arbitron PPMs, and it tied for 15th place (age 6+) in the March People Meter book. Monday afternoon, Clear Channel replaced it with a classic rock station named “The Band 103.7.” Since early 2008, the smooth jazz format has lost major-market outposts in markets such as Atlanta, Philadelphia, Washington, Houston and Denver.
