Serving a billion of anything is an impressive milestone. That Apple have managed to hit that figure in what is a comparatively short space of time makes it all the more impressive. The app download that took the number up to the all important 9 figures was made by Connor Mulcahey, 13, of Weston, CT. Being the grand prize winner of one billion app countdown contest, Connor will walk away with a $10,000 iTunes gift card, a Macbook Pro and a Time Capsule. The app he downloaded was Bump, by Bump Technologies. With the popularity of the app store showing no signs of waning in the near future, I'm sure it won't take long for Apple to rack up another billion downloads.
