Have you ever wondered how to stay updated on music? Then there’s one place to go: Billboard Hot 100. It is a music industry record chart in the United States for singles, published weekly by Billboard magazine.The rankings are based on radio play, online streaming, and sales.In 1991, the weekly sales period was originally Monday to Sunday when Nielsen started tracking sales , but since July 2015, this has been changed to Friday to Thursday.”It’s surprising how much Billboard has evolved since I was a teenager,” Journalism Adviser Amy Gullett said. “We used to have to wait until Saturday mornings for the Top 40 to come on. Then we had to wait and listen through every song to see where our favorite song was in the list.”
The first number-one song of the Hot 100 was “Poor Little Fool” by Ricky Nelson on August 4, 1958. As of the issue for the week ending October 10, 2015, the Hot 100 has had 1,047 different number-one hits. Its current number-one is “The Hills” by The Weeknd. At number 2 is Justin Bieber’s “What Do You Mean?” Number 3 is “Can’t Feel My Face” by The Weeknd.
