Kent had spent a number of years previously working in the music industry at both
EMI and
Phonogram records and had developed the report initially as a hobby. The Kent Music Report was first released on a commercial drive basis in July 1974 and was offered for subscription. The report data was initially based solely on radio station charts from around the country, which were then amalgamated using a points based ranking system that Kent had developed. These radio station charts were compiled primarily using data collected from local record stores and, as such, were based primarily on retail sales (i.e. they were not airplay charts). In 1976, as funding from subscriptions grew, Kent himself started collecting sales data from retail stores to supplement the radio station charts (which were also based on sales data leaving the ARIA Charts as the only nationally recognised chart publication. ==Further chart work published by David Kent==
