Sir Martin Sorrell's career needs no introduction: from years spent at Saatchi's and WPP, he has developed a keen advertising acumen and the experience to rival any other leading marketing personality.

Sir Martin believes there are two worlds of advertising: the analogue "old world" which has very little if any growth, and the digital "new world" where brands need to focus their efforts in order to stay competitive. In this episode, he tells us how digital is changing our ways of working and how he's leveraging it in his new project, S4Capital Group.
