The 72-player tournament, staged by the PDC and broadcast live on Sky Sports, is held throughout December and January, and will now be known as the William Hill World Darts Championship.

It is the online firm’s second darts sponsorship, following the three-year sponsorship of the Grand Slam of Darts at the Wolverhampton Civic Hall from 2011 to 2013.

Andy Lee, managing director of William Hill Online, said: “Our online business has shown strong growth in recent years and we believe sponsorships like this will help us reach new audiences and continue to help us grow.”

PDC chairman Barry Hearn (pictured with William Hill Online CMO Kristof Fahy) added: “With over 50,000 fans attending live and hundreds of millions more watching on Sky Sports and around the world, the William Hill World Darts Championship has an amazing global reach.”
