Billboard Hot 100
Although officially all three charts had equal importance, many chart historians refer to the Best Sellers In Stores chart when referring to a song’s performance prior to the creation of the Hot 100.  Billboard eventually created a fourth singles popularity chart that combined all aspects of a single’s performance (sales, airplay and jukebox activity), based on a point system that typically gave sales (purchases) more weight than radio airplay.  On the week ending November 12, 1955, Billboard published The Top 100 for the first time.  The Best Sellers In Stores, Most Played By Jockeys and Most Played In Jukeboxes charts continued to be published concurrently with the new Top 100 chart.
