The new "CAN DO DECODED" brand book by O₂ and Serviceplan Bubble answers the question of what it takes to be a game changer. Bestselling author Benjamin von Stuckrad-Barre interviewed five game-changing personalities who have made an impact on our world, shaped our culture, and transformed their success stories into literary portraits on 388 pages. In the process, it becomes apparent that these personalities are also characterized by a can do mentality that reflects the brand's attitude and values. The actual DNA of the ‘Game Changers’ was extracted from saliva samples and added to the book's printing ink. In addition to the print version, CAN DO DECODED is also available digitally and as an audio book to the more than 7,000 Telefónica employees.
