The networks are now operating in over 40 countries, encompassing over 5,000 people. Prior to Mark's Isobar role he spent 18 months as Global CEO of WPP's market research agency, Research International. In hindsight he's not quite sure why. Before his WPP adventure Mark spent 13 years involved with the development of the Bartle Bogle Hegarty agency group ( 1993 - 2006 ). Joining as member of BBH's management team these years saw the agency start its international expansion and the formation of its media agency ( Motive ), which Mark led.
