There's no doubt that the digital magazine's road to success has been a bumpy one. The original -- and still the main -- idea was to push content creators and publishers forward in the paperless era, but there's been many doubters and fallen soldiers in the process. While Apple hasn't been the only outfit looking to bring the magazine to the small screen, the introduction of the Newsstand app in iOS 5 aimed to give digitized publications a place to shine on their own. According to AllThingsD, the shelf isn't just a real estate hog on your springboard, it's actually helping to boost sales; Popular Science alone has seen an uptick in subscriptions on the order of 11,000 since the app launched, and signs of slowdown are nowhere to be spotted. PopSci's results may not be found in every publishing house, but it's as solid a sign as any that the tactic may be working. Hit the source link for that whiz-bang chart action.
