Adidas pays $240 million to acquire Runtastic

Since Under Armour acquired a series of popular fitness apps earlier this year, Adidas made the move this month to acquire Runtastic. Of course, Runtastic is more than an app. It's an ecosystem of apps, wearable devices, and engaged fitness bloggers and users who are willing to invest the time and energy to use tracking devices and gadgets to improve their fitness (or simply to help stay motivated).
