Pop 100

The Pop 100 was a songs chart that debuted in February 2005 and was released weekly by Billboard magazine in the United States until its discontinuation in 2009. It ranked songs based on airplay on mainstream top 40 radio stations, singles sales, and digital downloads.

History

The Pop 100 was conceived by Michael Ellis, and was first published in the Billboard issue of February 12, 2005.^[1] It was created to focus "on the songs with the greatest mainstream appeal, while the Hot 100 will be driven by the songs with the highest song rotations," according to Billboard chart editor Geoff Mayfield. In a press release about the new chart, he also stated that "the Pop 100's construction also makes sense when you notice the high correlation between the songs with the most top 40 plays and the best selling digital tracks."^[2]

The Pop 100 used only mainstream radio impressions data,^[3] derived from the Pop 100 Airplay chart. Its calculation also considered digital and physical sales.^[4] When the Pop 100 was first published, the Hot 100 changed its format as well. Digital downloads were incorporated into the equation which tabulates a song's rank on the chart. Prior to this, only radio airplay and physical singles sales were used to determine positions.^[3]

A Pop 100 Airplay chart was created alongside the Pop 100. It measured mainstream top 40 radio airplay and was the successor to Top 40 Tracks, the Billboard chart that formerly tracked airplay at that format after the Hot 100 panel was expanded to include a broader range of stations.

Discontinuation

It was stated by Billboard on June 10, 2009 that the Pop 100 was discontinued: "In place of the chart, which launched in 2005 and more recently had more mirrored the Hot 100 in light of heightened digital sales, the airplay-only plays-based Mainstream Top 40 survey, which began in 1992, will track the progress of songs across U.S. pop radio."^[5] Since digital sales have become a bigger factor in the compilation of the Hot 100, the dominance of R&B and hip-hop on that chart has reduced, which in large part had rendered the Pop 100 redundant. The Pop 100 continued to be published on billboard.biz until June 26, 2010.
