Mobile Augmented Reality has gone mainstream.

Canadian pop sensation Justin Bieber’s new album “Believe” has added content hidden that can be unlocked by fans using Augmented Reality developer Blippar’s app.

The content developed by Blippar allows fans to point their mobile phone at the cover of the new album, poster or advert in order to get access to track samples, photographs of Justin Bieber, competitions and a link through to iTunes to allow consumers to buy the album.
