Bray said many more school-age people were getting into the sport via academies rather than the pub.
“Now these guys can’t drink or anything so that pub element is dropping out of the game a lot,” he said.
Bray welcomed seeing a more professional edge to the sport, saying this attracted more money and sponsorships.
“Who would’ve thought you’d be a millionaire playing a game of darts? That’s how far the sport has come.”
Bray said Ally Pally, the venue for the festive tournament since 2008, still promised to be the “biggest party in the world”.
He said: “You’ve got 5,000 people dressed up in various types of costumes, you’ve got power rangers, you’ve got people dressed up as Jesus, you’ve just got everything there.
“It’s such an exciting place to be, the noise and the buzz is just out of this world.”
The 2025 PDC World Championship begins on Saturday and the tournament ends on Friday 3 January.
