For a mobile game with such a curious premise -- fling birds at green pig heads and break stuff in the process -- it's done phenomenally well. The original game was the first mobile game to hit one billion downloads, it was the first mobile game to be played in space, and it's even been downloaded in the remotest corners of Antarctica.

The game has seen over 4.5 billion downloads to date, but while the games themselves have become less of a draw over time, the entire Angry Birds franchise shows no signs of slowing down. There's been a surprisingly successful movie -- leading to a sequel -- not to mention a veritable mountain of merchandise, and of course, multiple PR stunts. The Venting Machine was a major Times Square draw last month, while the franchise simultaneously tapped into the power of online influencers with the launch of a fleet of anger-powered scooters (aka Rage Riders).

But it's also capitalized on its success for good. An in-game event for Angry Birds 2 recently called on players to show support for UNICEF's Education in Emergencies fund by popping 10 billion pigs, where upon Rovio -- Angry Birds' developer -- would make a $100,000 donation to the charity. Players, predictably, absolutely smashed that goal.

Back in 2014, we asked if the era of Angry Birds was over. Well, more fool us. With AR and VR spin offs and the game available on every conceivable console and the second movie performing so well, it's safe to say the age of the angry bird will spread well into the next decade, too.
