The single sold 465,000 downloads in its first week of digital release, the third-largest number of download sales in a single week overall, and the largest single-week and debut-download totals by a group in the history of digital-download sales tracking, reaching number one on the U.S. Billboard Hot 100 and Pop 100. It became the group's first U.S. number one, holding the spot for twelve consecutive weeks.[22] Having been dethroned to number two by the other Black Eyed Peas' song, "I Gotta Feeling", it is the second longest running number one song of 2009 on the chart, behind "I Gotta Feeling", and the first song to spend at least twelve weeks at number one since Mariah Carey's "We Belong Together" in 2005. The chart week of May 30, 2009 "Boom Boom Pow" became only the fifth song to top both Billboard's Mainstream Top 40 and Rhythmic Top 40 charts in the same week, reaching an estimated audience of 99 million on U.S. radio that week.[23]
