To muddy the waters, while the original Angry Birds app continued updating for three years, numerous spin-off apps were released alongside it between 2010 and 2015, including  Angry Birds Seasons, Angry Birds Star Wars, and Angry Birds Transformers. But it wasn’t until July 2015 when Angry Birds 2, the first real sequel to the game was released.

What’s more, because Angry Birds was primarily an iOS game, before being ported to Google Play, Chrome, and other platforms, it’s been ingrained in people’s brains at different times.
