The station started off as a separate website named ejazz as an accompaniment to the now defunct 102.2 Jazz FM and 100.4 Jazz FM stations in London and the North West respectively. GMG Radio revamped the site in 2004 and in 2005 when the London Jazz FM station was replaced with 102.2 Smooth FM, the ejazz website adopted the Jazz FM name and moved to jazzfm.com. Jazzfm.com also took up DAB slots in Yorkshire, South Wales and the Severn Estuary to relay the Blue Room stream of smooth jazz and funk music from the website at a higher bitrate, which were left vacant by the defunct Smooth Digital radio station.
