Since Katy Perry's Capitol Record debut in 2008 with "One of the Boys," she has racked up a cumulative 35 billion streams alongside worldwide sales of over 45 million adjusted albums and 135 million tracks with her albums "One of the Boys," "Teenage Dream," "PRISM," and "Witness," and her latest singles, "Never Really Over" and "Small Talk." She is the most-followed person globally on Twitter and was the first to reach 100 million followers. Katy was the first female artist to have four videos surpass a billion views each. Her videos for "Firework" and "Last Friday Night" have over one billion views, while "Roar" and "Dark Horse" have surpassed the two billion mark. Katy's 2015 Super Bowl performance is the highest-rated in the event's history. She is one of only five artists in history to have topped 100 million certified units with their digital singles – and the first-ever Capitol Records recording artist to join the elite RIAA 100 Million Certified Songs club.
