SAN FRANCISCO, March 21, 2013 /PRNewswire/ -- The availability of content anywhere and the rapidly increasing number of devices people use have changed the landscape for publishers, developers and advertisers dramatically. Mobile devices and apps are now a feature of everyday life; in fact, it is projected that by the end of 2013 the number of mobile devices will exceed the number of people on earth and close to two million apps will be available across the Apple App Store and Google Play.
