To celebrate 50 years of the Billboard Hot 100 chart, 17 Tracks will highlight the chart's record breakers, chart toppers, and milestones for the next two weeks. Perhaps the most important record is that of most #1 hits of all time. There's a bit of controversy surrounding the inclusion of Elvis Presley. The Hot 100 was first complied in August of 1958 by combining the airplay, jukebox play, and sales. Ten of Presley's 17 #1's came before the creation of the Hot 100 but reached pole position on the pop chart. Some chart watchers count pre-Hot 100 hits while some do not. Here, we will. Elvis is the freaking King of Rock n' Roll; how can we not include him?
