Guy Phillipson

Chairman of Internet advertising regulator,

Guy Phillipson is a veteran pioneer and inspiring leader in the digital advertising industry.

In 2019, Guy was appointed Chairman of, the UK internet advertising regulator which sets standards and good practice for digital ad trading – keeping ads away from all types of harmful content.

During 2017 and 2018 Guy was Chairman of the Hearst-owned digital advertising agency iCrossing UK, whose key clients include Barclays Bank, L’Oreal and Marks & Spencer.

But Guy’s career-defining role was as trade body CEO at the Internet Advertising Bureau UK (IAB), from 2005, spanning a period of explosive growth in digital media. Under Guy’s leadership, the IAB inspired marketers, agencies and publishers alike to take full advantage of the opportunities afforded by digital media – as, in turn, Web 2.0, social media, video, programmatic display, and mobile advertising evolved to dominate marketing communications. By 2016 digital ad spend represented 50% of all ad investment in the UK, totalling £10 billion.

Prior to focusing on digital media at JICWEBS, iCrossing and the IAB, Guy gained broad media experience as Head of Advertising at Vodafone UK and in other marketing roles at The Marketing Store, Barclays Bank and The Granada Group.
A man of eclectic interests – from jazz to theatre, from cycling to birds – Guy divides his time between Oxfordshire and the Isle of Wight, with his wife, Rebecca. They have two children, Susannah and Jasmine.
