Have you played Kim Kardashian: Hollywood yet? If you’re involved in digital music marketing and/or artist management, you probably should. The mobile game has been a runaway success on iOS and Android, sparking (admittedly overblown) analyst predictions that it could make $200m of revenues in its first year, with a big chunk of those going back to Kardashian herself. The game is made by mobile firm Glu Mobile, and now the Financial Times says that rivals are eager for their own celebrity licensing deals. “In the future, every movie, movie star and brand will have their own messaging apps just like they have their own websites now,” says one developer. “The hope in the [mobile] industry is that if you see a game affiliated with a star or a movie, the fact that it is familiar to you may pique your curiosity,” says another, suggesting that deals are shifting from $1m+ advance payments from developers to stars to more of a revenue-sharing model. Few music stars are truly mainstream enough to drive Kardashian-sized success on the app stores, but we think there’s scope for a handful to try.
