Wenda Harris Millard, who joined Martha Stewart Living Omnimedia in the summer of 2007 and became its co-CEO a year later, leaves the tower that proper etiquette built to work as president of Media Link LLC. Her new company specializes in media representation and strategic advising of media outlets.

“I am enormously excited about contributing to the quality counsel and implementation services Media Link provides to its impressive roster of international clients,” Millard, who served as chief sales officer at Yahoo before coming to MSLO, said in a statement. “I am as passionate as I have ever been about the media, marketing and advertising businesses, and I cannot think of a more opportune time or a more well-positioned company than MediaLink with which to apply my skills and knowledge in helping major global companies plan and execute intelligent marketing strategies.”

Her move, however, isn’t all gum drops and chocolate. According to the New York Post, tensions between Millard, the other co-CEO Robin Marino and Martha Stewart drove the former to MediaLink. Last week, Millard’s deputy Jacki Kelley, who came over from Yahoo to serve as MSLO’s executive vice president of media sales, left the company for a position at an advertising agency. Her boss didn’t take much time to follow her out the door.
