JazzWeek was founded in August 2001 after trade publication The Gavin Report ceased publishing a jazz radio chart, and has published weekly jazz radio airplay charts since that time and smooth jazz charts until February 2012.
From August 2001 to November 2004, JazzWeek published jazz and smooth jazz charts using airplay reports submitted by stations. From November 2004 until February 2012, data for JazzWeek reports came from Mediaguide, Inc., a now-defunct airplay monitoring service.
After Mediaguide’s demise in February 2012, JazzWeek returned to publishing the weekly jazz chart using airplay reports submitted by stations. The smooth jazz chart was discontinued.
