Adele came, Adele saw, Adele conquered.
"Hello" is Adele's fourth career No. 1 single, following "Rolling in the Deep," "Someone Like You" and "Set Fire to the Rain," all from her 21 album. Her most recent Top 10 hit was "Skyfall" in 2013.
Meanwhile, "Hello" is the first single in the Nielsen era to be the first song to sell over 1 million downloads in its first week. Flo Rida's "Right Round" previously held the record for single-week download sales. In addition, "Hello" collected 61.6 million U.S. streams in its first week, including 20 million on-demand streams, per Billboard.
"Hello" is just the 24th song to debut in the top spot of the Billboard Hot 100 chart. The most recent No. 1 debut was Justin Bieber's "What Do You Mean?," which was his first No. 1 single in September (Bieber's new single "Sorry" also debuts on this week's Hot 100 chart, at No. 2).
Adele's next album, 25, is due out Nov. 20, and is expected to cross the million-sales mark in its first week. The U.K. superstar is set to perform at New York's Radio City Music Hall on Nov. 17 for an NBC TV special, and will play Saturday Night Live on Nov. 21.
