According to sources, Robin Domeniconi (pictured here), Microsoft's vice president for U.S. Advertising Sales, Publishing, and Marketing, will be leaving the company.
While Domeniconi is leaving, sources said Microsoft is close to hiring Carolyn Everson of MTV Networks to head up its online ad sales force globally.
While the deal is not done, Microsoft has been looking to fill the key slot for more than a year.
Everson (pictured here) is currently executive vice president of Strategy and Operations for the MTV Networks U.S. ad sales department.
Interestingly, sources also said Everson was also on the list of candidates Yahoo is still perusing to fill the key U.S. ad sales jobs after Joanne Bradford departed recently for Demand Media.
Domeniconi, a former Time exec, who came to Microsoft in 2008, announced her departure on Wednesday, said insiders.
She has been in charge of executing sales and marketing strategies for Microsoft's media properties, including MSN, Windows Live, Xbox Live, and Bing.
A Microsoft spokesman declined to comment.
