Microsoft is losing its general manager of global media, Megan Hanley, who is planning to leave the company at the end of October.
"She would like to get back to her roots of working with earlier-stage companies in building their brands and businesses through consumer marketing," said a Microsoft spokeswoman via email.
Ms. Hanley has been at the company since June 2008 and was promoted after a little more than a year from her previous role as general manager of Windows Digital Marketing. Prior to joining the company, Ms. Hanley spent time at NetRead and Esurance.
It's understood that the company is searching for a successor.
This May, the company split duties on its global media account between Publicis Groupe 's Starcom Mediavest, which handlies global strategy and planning, as well as buying in the U.S., and incumbent Universal McCann, which continues to manage media planning and buying outside North America.
Microsoft stressed that Ms. Hanley's move would not affect the company's media agency relationships. Said the spokeswoman: "We are pleased with the progress, collaboration and execution of our media team and media agency partners. SMG has proven to be an invaluable new partner working in tandem with UM outside of the U.S. and our creative agencies to drive exciting and engaging ways to deliver content to our customers in today's dynamic media marketplace."
Microsoft, which encompasses the Microsoft, Bing and Xbox brands, spent around $1 billion in domestic media in 2010, according to the Ad Age DataCenter.
Other recent leadership changes include Mich Mathews, who announced plans to retire in March 2011. Chris Capossela succeeded Ms. Mathews as CMO.
