After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry and released her first Internet single "Ur So Gay" that November, which garnered public attention but failed to chart. She rose to fame with the release of her second single "I Kissed a Girl" in 2008, which went on to top international charts. Perry's first mainstream studio album One of the Boys followed later that year and subsequently, became the thirty third-best selling album worldwide of 2008. It was accredited platinum certification by the Recording Industry Association of America, while "I Kissed a Girl" and her second single "Hot n Cold" both received multi-platinum certifications. Her sophomore studio album Teenage Dream was released in August 2010 and debuted at number one on the Billboard 200. The album included hit singles "California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)" , all of which topped the charts on the Billboard Hot 100, making the Teenage Dream album one of only nine albums to ever produce four or more Hot 100 number ones.With "E.T." at number one on the chart of May 12, 2011, Perry became the first artist in history to spend a whole year, 52 consecutive weeks, in the top 10 of Billboard Hot 100.
Perry signed to Columbia Records in 2004. However, the label was not amenable with her vision, not putting her in the "driver's seat" Instead, one of Columbia's ideas was to pair Perry with the record production team The Matrix, who was working on an album, to serve as its female vocalist. Although the album was later shelved,she caught the attention of the music press: Her burgeoning music career led to her being named "The Next Big Thing" in October 2004 by Blender magazine. With no album project ongoing, Perry began recording her own. Eighty percent completed, however, Columbia decided not to finish it and dropped her off the label.While waiting to find another label, she worked in an independent A&R company called Taxi Music. In 2006, Perry was featured in the tail-end of the video to P.O.D.'s single "Goodbye for Now". She made a cameo appearance in Carbon Leaf's video, "Learn to Fly".
