A while ago PUBG plastered ads for their Berlin Invitational. While they were ads related to the game, the incrementally added them EVERYWHERE!
First they're on a bus-stop wall, that's thematic okay. Then they're on random walls - getting annoying. Then the loading screen and the parachutes, nows it's annoying. Like, guys I'm from the US and I don't want to go to your stupid competition!
I can imagine walking down the street in Call of Duty game or something like Cyberpunk 2077 and seeing ads overlaid on wall textures of buildings.
