"Apologize" was OneRepublic's breakout hit. In the United States, "Apologize" peaked at number two on the "Billboard" Hot 100 for four non-consecutive weeks, first blocked from the top spot for two weeks by Chris Brown's "Kiss Kiss" and then for two weeks by Alicia Keys' "No One". It spent 11 weeks at number three and 25 weeks inside the top 10 and peaked at number three for 10 weeks on the Hot 100 Airplay. It also topped the "Billboard" Pop 100 and became the third single from "Shock Value" to have topped the chart. It also became the album's first number-one single on the "Billboard" Adult Top 40. It is also the second consecutive single from "Shock Value" to reach number one on the US Mainstream Top 40 radio. It became only the tenth song to sell over 5 million by May 2011 in the US. As of February 2014, it had sold 5,819,000 copies. In late 2009, the song was ranked in 10th place on the Billboard Hot 100 Decade-End chart, making it the highest-ranking song and the only top-10 ranking song on there to not top the weekly Billboard Hot 100 chart.
