Vreo is building an infrastructure to enable in game advertising on the game engine level. They are creating a B2B marketplace where advertisers can purchase ads deeply embedded in the game systems that do not compromise the user experience like many pop up ads would. Ads can be shown example on billboards or walls within the game or as sponsor logos on cars in a racing game or other various in-game items. Imagine that every time you play a game the ads can show up seamlessly in the game environment and views of these ads are then stored on the blockchain to provide full transparency and avoid ad fraud so that the advertisers can be sure that the views really took place.
