You can do the math. 50 million downloads in 35 days means 1.43 million downloads a day, or 59,500 downloads an hour, or close to 1,000 a minute (991.7, to be exact). That's actually slowed down, though: it hit 10 million downloads or more then 3 million a day in the first 3 days.
Still, it's amazing, and available on iOS, Android, PC and Mac. Eventually, it will make it to Windows Phone, as well, it's been confirmed by Rovio CEO Mikael Hed.
Considering how many downloads the app series has had overall, 50 million is chump change. Angry Birds in its earlier forms (the original, Angry Birds Seasons, Angry Birds Rio) along with Angry Birds Space has been downloaded 750 million times.
Extrapolating those values (which of course, isn't really valid), in less than half a year, downloads of Angry Birds Space could lead to the series passing the 1 trillion download mark. In a blog post, Rovio said,
“This has been simply amazing, and the whole Rovio team is thrilled to see such a fantastic reception for the game. We extend our deepest gratitude to all fans of Angry Birds everywhere. While numbers like this certainly say something about the popularity of Angry Birds, for us the main goal is to keep creating fun new experiences that everybody can enjoy! We just launched the first free update for Angry Birds Space, with plenty more surprises in stock.”
By "first free update for Angry Birds Space," the company was referring to a "pack" of 10 new levels, which have been released for iOS and Android.
What could that mean? We already know the franchise is heading into animation. Where else could it go?
