Marissa Mayer’s appointment caps a tumultuous year at Yahoo. In May, Scott Thompson resigned as CEO after less than 6 months on the job as a controversy flared up over his academic credentials.
Thompson replaced the controversial and occasionally foul-mouthed Carol Bartz, fired in September after failing to revitalize Yahoo.
“She’s going to bring in a different perspective. It’s pretty clear Yahoo needs a new direction and really a new vision,” said Paul Buchheit, a Google engineer who helped create Gmail and now a partner at startup-incubator Y-Combinator.
