From the article posted on Billboard (November 3, 2022):
Airplay charts (based on audience and/or plays) finalized Monday, Nov. 7 (dated Nov. 12), will be the first using Mediabase data. Individual-format airplay charts dated Nov. 12 will reflect airplay tracked Monday, Oct. 31, through Sunday, Nov. 6. The Nov. 12-dated
Radio Songs chart, which serves as the airplay chart component to the all-genre, multi-metric
Billboard Hot 100(which also blends streaming and sales data, as compiled by Luminate), and reflects a Friday-Thursday cycle, will incorporate BDS data for Oct. 28-30 and Mediabase data for Oct. 31-Nov. 3 (with Mediabase data to power Radio Songs thereafter).
Billboard will continue to maintain unique charts and reporter panels, separate from Mediabase’s, for all formats. Upon the change,
Billboard will continue to incorporate all current reporting stations that are also monitored by Mediabase for
Billboard’s charts.
Billboard and Mediabase aim to add additional reporting stations going forward.
Meanwhile, weekly and year-end
Billboardcharts will continue to be compiled via the same parameters previously applied with BDS data. (Year-end airplay rankings will continue to reflect songs’ activity while on corresponding weekly charts.)
Along with Radio Songs,
Billboard’s United States-based airplay charts encompass: Pop Airplay (Mainstream Top 40); Adult Pop Airplay (Adult Top 40); Adult Contemporary; Country Airplay; Rock & Alternative Airplay; Alternative Airplay; Adult Alternative Airplay (Triple A); Mainstream Rock Airplay; R&B/Hip-Hop Airplay; Mainstream R&B/Hip-Hop Airplay; Adult R&B Airplay; Rap Airplay; Rhythmic Airplay; Latin Airplay; Regional Mexican Airplay; Latin Pop Airplay; Latin Rhythm Airplay; Tropical Airplay; Christian Airplay; Christian AC Airplay; Gospel Airplay; Dance/Mix Show Airplay; Smooth Jazz Airplay; and the seasonal Holiday Airplay chart.
