Probably one of if not the most downloaded app of 2016. An early attempt at using augmented reality technology in a game. Initially it caused a huge spike in Nintendo's share price, followed by an equally rapid collapse once people realised the Nintendo company did not own the app.
Compare the above to the spike in Google searches:
While the number of searches has fallen to close to zero Nintendo's share price remains about 67% higher than before the release of Pokemon Go (around 25,000 after, around 15000 before). So overall it was a good event for Nintendo share holders.
