"The past is just as important as the future" - Zak Brown (2/4)

On the day of the announcement of his December 31, 2016, resignation as Group CEO of CSM (the global sports marketing agency), Zak Brown talks about the future of F1 and the potential of the sport's new investors, Liberty Media. In part 2, the conversation turns towards the opportunities for enhanced digital media coverage, the importance of the sport's heritage, the underplaying of GP2 and GP3, the ideal number of races in an F1 season and whether or not the gambling industry will play a role in F1's future. Zak - one of the most successful F1 marketeers of recent times - talks to Peter Windsor.
