Yahoo CEO Carol Bartz and company board members addressed investors Thursday at the company's annual shareholder meeting. Despite majority support for Bartz and other board members, a certain level of discontent was palpable among investors, and one particular shareholder called for an end to Bartz's tenure. A degree of discontent among some Yahoo stake holders has sprouted from underperformance and an inability to keep up with competitors. To kick off the presentation Thursday, Yahoo introduced itself as "The Premier Digital Media Company."
