SEATTLE (AP) - The top executive at Microsoft Corp.'s MSN media network is leaving for Los Angeles advertising startup Spot Runner, the software maker said Thursday.
Joanne Bradford's departure follows a management shake-up in Microsoft's online business in February, when Bradford's then-boss Steve Berkowitz left. He had arrived in 2006 and was charged in part with expanding the audience on Microsoft's disparate MSN and Windows Live sites.
Bradford's decision also comes six weeks after Microsoft's unsolicited $40-billion bid for Web portal business Yahoo Inc. The takeover offer is widely seen as an admission that Microsoft's hope of challenging Google Inc.'s search and advertising dominance with a homegrown solution was gone.
