Katy Perry cemented her status as a best-selling superstar with the global success of her second studio album, "Teenage Dream," which debuted at No. 1 in eight countries and spent more than two years on Billboard's Top 200 album sales chart. She became the only female artist to have five No. 1 singles from one album on the Billboard Hot 100 chart ("California Gurls," "Teenage Dream," "Firework," "E.T." and "Last Friday Night"). The special edition, "Teenage Dream: The Complete Confection," added "Part of Me" and "Wide Awake" to Perry's list of nine Top 40 chart-toppers (dating back to her multi-platinum debut album, 2008's "One of the Boys," which generated four hit singles: "I Kissed A Girl," "Hot N Cold," "Thinking of You" and "Waking Up In Vegas").
"Roar," the first single from her new album, "Prism," became Perry's 10th No. 1 Top 40 track after debuting at No. 1 on iTunes in 68 countries with 557,024 downloads in its first week of release, the biggest digital song sales week of 2013. A successful follow-up single, "Unconditionally," was released in late 2013, followed by "Dark Horse," which helped Perry set the record at Top 40 for most total weeks (46) at No. 1 in the Billboard airplay chart's archives.
She is the first artist to surpass the 70 million digital award threshold, counting digital downloads and on-demand streams – 20 million ahead of any other artist.
