Karnstedt Out at Yahoo, Microsoft Vet Bradford In

Joanne Bradford is back among mere portals.

The former chief media officer of MSN’s Media Network, who made a splash in May when she bolted Microsoft to accept a national sales gig with new hotness Spot Runner, has accepted a gig with Yahoo as SVP of U.S. revenue and market development.

Simultaneously, Yahoo said today that U.S. sales chief David Karnstedt has left the firm to join VC firm Redpoint Ventures as executive in residence. Karnstedt resigned earlier this summer but the company has kept that news under wraps while preparing for the transition.

Bradford will report to EVP Hilary Schneider and lead advertiser, small business, and HotJobs sales and go-to-market activities. Her job is a new one at the company, and will unify all of Yahoo’s U.S. advertising sales and go to market activities, a spokesperson said.

Separately, Spot Runner stated it has hired Jon Rosen, formerly head of sales for automotive ad network Autobytel, to a senior sales and business development role. He previously led strategy and business development for AOL’s search operation. It also hired Elizabeth Carrasco, formerly of Authenticlick, as VP of online engineering. Both will work in the company’s local marketing unit.

Spot Runner spokesperson Rosabel Tao said Bradford’s departure was a personal decision and had nothing to do with its recent 50 layoffs in various divisions. Those job cuts were part of a company-wide realignment intended to emphasize three areas: national marketing services, local marketing services, and technology.

The technology unit will focus on innovations including those involving data, analytics, and performance optimization.

“We’re certainly doing a lot of work developing new technologies focused on optimizing ROI for clients,” said Tao. “How do we bring the discipline and measurement of online advertising to offline advertising?” Bradford was not immediately reachable for comment.
