The changes to the Hot 100 will take place in the 8/11/07 issue. They've been running test charts all year long.
Historically, the Hot 100 formula has been roughly airplay (60%) and sales (40%). The new chart changes will adjust the chart back to it's more historic ratios.
Over the last year the chart had seen the ratio for airplay (40%-30%) and sales (60%-70%) change dramatically due to large digital growth in 2006 and 2007.
The breakout of the new Hot 100 formula will basically be airplay (55%), sales (40%) and on-demand streaming (5%).
Airplay will now include all BDS monitored stations regardless of whether they report to a specific format or not (it will also include the stations removed from the Country panel for not playing enough currents).
