The ad business is on the cusp of some serious change, and Christina Beaumier can't wait. The Vice President of Advertising Technology for AT&T Advertising and Analytics (which since the publication of this interview has been renamed Xandr) has seen the change coming for a while, having previously worked for publishers like Google and agencies like GroupM’s Xaxis. Beaumier is a big believer in the power of convergence -- the marrying of TV and digital. She has experience bridging different worlds: It was a Peace Corps mission in West Africa that set her on her career path. She talked recently with MediaVillage about industry trends, mentoring, leadership, gender equality in the workplace and much more.
