Growth. You don't have to be Gordon Gekko to recognize that exponential growth in revenues is the mark of both a buoyant industry and, on an individual level, a healthy participant within it. Kudos must, therefore, be handed out to all the top four app stores globally, as each one expended its total revenues by over 130 percent between 2009 and 2010. Interestingly, Apple's growth looks to be slowing down as the App Store begins to reach a saturation point on smartphones, while Nokia's Ovi Store and Google's Android Market blossomed during 2010 by multiples of 7.2 and 8.6 times their 2009 size. Apple's share at the top has shrunken as a consequence, a trend that looks likely to continue when Windows Phone 7's Marketplace and the Ovi Store are melded into one through this year and beyond.
