The music industry is currently intensely interested in the evolution of mobile advertising, and what it might mean for the business models of digital music services. With that in mind, keep an eye on Google’s new Art, Copy & Code initiative, which the company describes as “a series of experiments to re-imagine advertising”. Here’s more: “Some of these will include familiar brands like Volkswagen, Burberry and adidas—projects developed in partnership with their creative teams and agencies. Others will be creative experiments with innovative filmmakers, creative directors and technologists to explore how brands can connect with consumers through a whole range of digital tools—including ads, mobile apps and social experiences”. Volkswagen is first on board with a mobile app called Smileage, a social road-trip sharing app with Google+ baked in. We think there’s scope for some interesting brand-powered music apps here too.
