Apple's The App Effect video showcases the importance of apps in today's world

Earlier today at WWDC 2015, where Apple announced iOS 9, the company also mentioned that its App Store had reached 1.5 million apps - an impressive number. To celebrate this, Apple released a video titled The App Effect.

Like the first promo video for Apple Music (also released today), the App Effect video is made from a historical point of view, reminding us that, in 2007, when the original iPhone was launched, there was no App Store at all. Then, in 2008, when the App Store was first released, in only contained 500 apps. Now, 7 years later, the number has grown to 1 and a half million (including almost 200,000 educational apps), allowing people all over the world to benefit from the often brilliant ideas of developers (who, of course, are also people all over the world).

Interestingly, as you'll see in the video, astrophysicist and cosmologist Neil deGrasse Tyson believes that "apps plus handheld devices" are so important that they can be "put up there with the invention of the microscope and telescope."

We may now take apps for granted, but they certainly represent a revolution in their own way (we're talking about apps in general here, not just iOS ones).
