Media industry finds revenue in places it once scorned: The New Republic's move to New York reflects a changing approach to tap digital dollars.

Crain's New York reports:

Print ad revenue continues to slide, digital ad dollars are under pressure from automated exchanges that find the best audience at the lowest price, readers are moving to mobile devices—which have less room for ads—and ad agencies have new and cooler places to invest a client's money, like Twitter and Instagram.

At the same time, for the right kind of digital media property, experts see more reason for optimism than in past years. Atlantic Media, Gawker Media and Slate, to name a few, are all profitable and growing, as they draw on different revenue streams and build an advertising business in the face of competition from Facebook and Google. Even The New York Times, despite its latest round of layoffs last month, has seen digital ad growth for three quarters in a row and, at last count, a double-digit increase in online subscriptions.
