Ross Levinsohn, the interim CEO who was snubbed in the search for a permanent leader at Yahoo, is leaving the Internet portal.
Yahoo announced the departure in a securities filing on Monday.
With much fanfare, Yahoo appointed 37-year-old Marissa Mayer as CEO two weeks ago. Retaining Levinsohn would have been one of her first big triumphs.
Levinsohn, 48, had been head of Yahoo's global media business and had pushed the company to enter into exclusive partnerships with the likes of CNBC and Tom Hanks to create original content.
But Levinsohn was passed over twice by the company's board in favor of other top executives, including Scott Thompson, who resigned in May over discrepancies on his resume after just four months on the job.
