What if you could go to the movies for free, but every 15 minutes the film would stop for a commercial break? A few very cost-conscious people might tolerate it, but I reckon most would refuse to ruin their cinema experience that way. Similarly, there’s a good reason game developers dislike in-app advertisements: They distract your customers — and frequently discourage them from using your product. “Gamers want to game. So disturbing the gamer’s experience, even if it brings value, isn’t always the way to go,” wrote Avi Hadas, in a recent guest column on in-game advertising for VentureBeat. The stakes are high. In an industry concerned about churn, retention, and monetization of players, in-game ads might save your business — or end up killing it.
