In 2009, the group became one of only artists to have simultaneously held the No. 1 and No. 2 spots on the "Billboard" Hot 100, with their singles "Boom Boom Pow" and "I Gotta Feeling", with the next single "Meet Me Halfway" achieving similar success, from the album "The E.N.D.". These three singles topped the chart for 30 consecutive weeks in 2009. The album later produced a third Hot 100 number-one placement with "Imma Be", making the group one of few to ever place three number one singles on the chart from the same album before being followed with "Rock That Body" which managed to peak in the Top 10 of Hot 100. "I Gotta Feeling" became the first single to sell more than 1 million downloads in the United Kingdom.
