NEW YORK (AdAge.com) -- As the first photographer to serve as the editor of National Geographic, Chris Johns in his three-and-a-half-year tenure has brought a new vision to the publication. And it works. In a seriously down market, his ad pages and single-copy sales are up significantly. Just named Ad Age's Editor of the Year, Mr. Johns sat down to discuss his strategy for running a successful monthly magazine in an era of instant news. He also detailed the publication's online community-building efforts for consumer photographers.
