Apple on Friday initiated a countdown to 25 billion iTunes App Store downloads. The running total currently sits just under 24.3 billion downloads and Apple is offering a prize to the user who downloads the 25 billionth application. “As of today, nearly 25 billion apps have been downloaded worldwide. Which is almost as amazing as the apps themselves. So we want to say thanks,” Apple wrote on its website. “Download the 25 billionth app, and you could win a US$10,000 App Store Gift Card. Just visit the App Store and download your best app yet.”¬†Apple’s iOS App Store opened its doors in July 2008 alongside the launch of the iPhone 3G, and the company would later launch the Mac App Store in October 2010.
