here's a couple examples of companies using Pokémon Go for marketing in my country.
this online store promoting their powerbanks / portable chargers for phones using Pokémon Go teams (''Support your team!'')
McDonalds (''Big Mac, I choose you!'')
If you show a screenshot of you catching a Pokémon in these clothing stores, you'll receive a €20,- giftcard
the impact is unreal.
