Simon Waldman, the Guardian Media Group's former director of digital strategy and development, has published his first book Creative Disruption - Why You Need to Shake Up YourBusiness in a Digital World.
It examines the way traditional business models have been ripped up and new opportunities have been created. Waldman looks at businesses that have faced major challenges in the digital revolution, such as Encyclopaedia Britannica, Kodak, IBM, HMV and the turn around of Apple.
Waldman, who was launch editor of Guardian Unlimited in 1999, left GMG in May to become group product director for LoveFilm.
