Virgo was a popular commentator, with his famous “where’s the cue ball going?” catchphrase when a player was close to committing a foul.
Players and officials held a minute’s silence at the World Grand Prix in Hong Kong on Wednesday.
Seven-time world champion Ronnie O’Sullivan said: “Finished my match to get the news that JV has passed away.
“Such a great mate who I loved spending time with. Absolutely gutted.”
Four-time world champion Mark Selby said: “So sad to hear the news of the passing of John Virgo! Such a great guy and a huge character! He will be greatly missed! RIP JV.”
Former world champion Shaun Murphy, who worked alongside Virgo for the BBC, said: “I first met John in 1994, filming Junior Big Break. He then went on to become a friend and colleague.
“I learned so much from him whilst sharing a commentary box. The voice of snooker will be sadly missed.”
Virgo regularly took part in exhibition matches, playing trick shots and performing impressions of other players.
Former world champion Neil Robertson said: “He was a great character and an amazing pundit and commentator.
“I had the pleasure of sharing the booth with him during the World Championship a couple of years ago in which I got a huge appreciation for how good he was.”
A World Snooker statement read: “Everyone at World Snooker Tour is deeply saddened to learn of the passing of legendary snooker player and broadcaster John Virgo.”
Former world number three Neal Foulds said: “Terribly sad news that we have lost one of the greats of snooker in John Virgo.
“JV was incredibly generous, kind and funny. He was also a wonderful player and commentator. Thanks for all the great memories JV.”
Virgo, who was born in Salford in 1946, is survived by wife Rosie and children Gary and Brooke-Leah.
