At Thursday's annual shareholders meeting, Yahoo Inc. interim CEO Ross Levinsohn talked like someone who expected to be running Yahoo for more than just a few months. But Yahoo gave no indication on when it might name someone permanent. Here's a look at Yahoo's CEO over the years:
Tim Koogle — 1995-May 2001. Began tenure shortly after Yahoo was incorporated in March 1995. Announced in March 2001 that he would step down after a replacement is found.
Terry Semel — May 2001-June 2007. Hired from Warner Bros. Stepped down under shareholder pressure.
Jerry Yang — June 2007-January 2009. Company co-founder and de facto CEO until Koogle started. Agrees to resign under pressure in November 2008, pending appointment of replacement.
Carol Bartz — January 2009-September 2011. Hired from Autodesk Inc., a design and engineering software company. Fired after failing to revive the company.
Tim Morse — September 2011-January 2012. Interim CEO, to retain chief financial officer role after new CEO Scott Thompson takes over next Monday.
Scott Thompson — January 2012-May 2012. Hired from eBay Inc.'s PayPal. Left after disclosure that his official biography included a college degree he never received.
Ross Levinsohn — May 2012. Named interim CEO. Joined Yahoo in November 2010 following a stint running Internet services at News Corp.
