What is Pop Airplay?
The '''Pop Airplay chart''' (formerly '''Mainstream Top 40''' and '''Pop Songs''' chart) is an [[airplay]] chart from [[Billboard (magazine)|''Billboard'' magazine]]. People often mistook it for the now discontinued [[Pop 100 Airplay|Pop 100]] chart. The chart is solely based on radio airplay, ranking the week's hottest pop songs based on monitored radio detections from a panel of 200 Top 40/CHR radio stations in the United States as measured by Nielsen BDS [[Nielsen Broadcast Data Systems]]. [[Arbitron]] sometimes refers to the format as [[contemporary hit radio]]. The chart was launched the week of October 10, 1992, along with the [[Rhythmic Songs Chart]] as a way to distinguish stations that played a broad based mix of current hits from those who focused on offering a direction centering on R&B/Hip and Dance material. {{music-stub}} [[Category:Pop music]] [[Category:Billboard charts]]
