List of Billboard Hot 100 chart achievements and milestones  This is a comprehensive listing that highlights significant achievements and milestones based upon "Billboard" magazine's singles charts, most notably the "Billboard" Hot 100. This list spans the period from the issue dated January 1, 1955 to present. The "Billboard" Hot 100 began with the issue dated August 4, 1958, and is currently the standard popular music chart in the United States. Prior to the creation of the Hot 100, "Billboard" published four singles charts: "Best Sellers in Stores", "Most Played by Jockeys", "Most Played in Jukeboxes" and "The Top 100". These charts, which ranged from 20 to 100 slots, were phased out at different times between 1957 and 1958. Though technically not part of the Hot 100 chart history, select data from these charts are included for computational purposes, and to avoid unenlightening or misleading characterizations. All items listed below are from the Hot 100 era, unless otherwise noted (pre-Hot 100 charts). In 2008, for the 50th anniversary of the Hot 100, "Billboard" magazine compiled a ranking of the 100 best-performing songs on the chart over the 50 years, along with the best-performing artists. In 2013, "Billboard" revised the rankings for the chart's 55th anniversary edition. In 2015, "Billboard" revised the rankings again. In 2018, the rankings were revised again for the "Billboard" chart's 60th anniversary. Shown below are the top 10 songs and top 10 artists over the 60-year period of the Hot 100, through July 2018. Also shown are the artists placing the most songs on the overall "all-time" top 100 song list.  * – re-released Source:  Source:  Source:  Pre-Hot 100 Notes:  Source:  Source:  The following songs have the most weeks in the top ten.
