What happened: In June, Westergren, who co-founded the company in 1999, announced that he would be leaving the company after his second stint as CEO. He first served in the role from May 2002 to July 2004. In March of 2016, he replaced chairman, CEO and president Brian McAndrews in the position.
Of his exit, Westergren said, "I came back to the CEO role last year to drive transformation across the business," Westergren said in a statement. "We accomplished far more than we anticipated. We rebuilt Pandora's relationships with the music industry; launched a fantastic Premium on-demand service, and brought a host of tech innovations to our advertising business. With these in place, plus a strengthened balance sheet, I believe Pandora is perfectly poised for its next chapter."
