Angry Birds is a video game franchise created by the Finnish company Rovio Entertainment. The series focuses on multi-colored birds which try to save their eggs from green-colored pigs, their enemies. Inspired by Crush the Castle, the game has been praised for its successful combination of fun gameplay, comical style, and low price. Its popularity led to many spin-offs, versions of Angry Birds created for PCs and video game consoles, a market for merchandise featuring its characters, a televised animated series, and a feature film. By January 2014, there had been over two billion downloads across all platforms, including both regular and special editions. By July 2015, the series’ games had been downloaded more than three billion times collectively, making it the most downloaded freemium game series of all time. The original Angry Birds has been called “one of the most mainstream games out right now”, “one of the great runaway hits of 2010”, and “the largest mobile app success the world has seen so far”. An animated feature film based on the series was released by Columbia Pictures on 20 May 2016, and the first main-series sequel, Angry Birds 2, was released on 30 July 2015.
