Barry Hearn has been promoting sports for well over 40 years.

As the head of Matchroom Sport, he has revolutionised snooker twice and made his PDC Darts World Championship the second most viewed event on Sky Sports. He managed a stable of boxers in the 1980s and his son Eddie is now guiding the career of world heavyweight king Anthony Joshua among many others.

Now 70, Barry still describes himself as “an accountant from a council estate with a chip on his shoulder”. He still rallies against “the blazers” and still wants to change the sporting world on a daily basis.
