Of the 31 Triple Crown events under Hearn's leadership (including next week's Masters), all bar one (the 2012 BGC Masters) was sponsored by a betting company (96.8%).
Of the 96 ranking events/major invitational events held in Europe, 88 have been sponsored by betting companies (91.7%). This excludes events without a sponsor.
The only non-betting companies to sponsor an event in Europe in the last ten years are:
Wyldecrest Parks: 2
Kreativ Dental: 1
That, to me, is hugely concerning.
