Ms. Bradford was until recently vice president and director of North America advertising sales for McGraw Hill Cos.' Business Week.
Ms. Bradford, who will be based in San Francisco, will oversee MSN's Advantage Marketing program, which targets Fortune 100 companies and advertising and media agencies, and she will also develop customized ad solutions.
Jed Savage, the New York-based general manager for MSN field sales, and Bob Bejan, the Redmond, Wash.-based general manager for MSN strategic sales, will report to Ms. Bradford. She'll also work closely with the MSN team that develops next generation ad products and the central marketing organization at Microsoft's Redmond headquarters.
"We were looking for someone with deep experience in the media sales community and a world-class executive who can help us pull together all the assets we have to bring to large marketers in the U.S.," said Rich Bray, vice president of MSN.
Ms. Bradford will begin next month. MSN rival Yahoo! recently named Wenda Harris Millard to a top ad sales post. Mr. Bray said the timing of MSN's announcement was coincidental.
With the hire, Mr. Bray believes MSN "will be in a very good spot when the market comes back, we realize this is a very cyclical business and we're in a deep downturn."
Through its Advantage program and other content partnerships, MSN has built relationships with ESPN, First USA, Bank One and Toyota Motor Sales.
