"I Kissed a Girl" debuted at number 76 on the "Billboard" Hot 100. After a couple of weeks, the single hit the top 5, due to the rising digital downloads and increasing radio airplay. It continued to rise the next week, reaching #2 just behind her labelmate, Coldplay. The following week, the song reached the summit of the US chart, becoming the 1000th #1 song of the rock era (the 961st #1 on the "Billboard" Hot 100). In addition the song also gave the Capitol label two consecutive Hot 100 #1's, as the week's prior #1 was fellow Capitol artist Coldplay's "Viva la Vida", making it the first time since 1976 Capitol has had two back to back chart toppers on the Hot 100. The single also crossed over to Billboard's sister publication R&amp;R's Rhythmic chart in its July 5 issue, where not only did she have the highest debut ever for a non-rhythmic track, entering at number 26 with 1,065 spins, she also had the highest debut from a new artist in over five years. The bow is the best for a debut track at Rhythmic since Beyoncé entered at No. 21 with "Crazy in Love" in 2003. It also became the first song since Gnarls Barkley's "Crazy" to simultaneously appear on the Mainstream Top 40, Rhythmic, Adult Top 40 and Alternative charts. On July 26, 2008, the track also made history by reaching the number one spot on Billboard's Hot Dance Airplay chart by three weeks, a first for a solo act with a debut single. The song topped the Hot 100 for seven weeks in a row before finally being dethroned by Rihanna's "Disturbia". It is the second longest running number one on the Hot 100 of 2008 so far, with only Flo Rida's "Low" topping the chart for longer. The single has sold more than 2,500,000 downloads in the United States to date.
