Since its release in 2016, multiple real-life events and gatherings based on the augmented reality (AR) mobile game Pokémon Go have been held by its developer Niantic Labs outside of unofficial player gatherings. Typically, the events involve increased in-game rewards for participating players and are often held in cooperation with local organizations or governments. Niantic estimated that Pokémon Go live events in 2019 generated about $249 million in tourism revenue: $120 million in Chicago, $71 million in Montreal, and $56 million in Dortmund.
