Davis BBC boom 1981–1989
BBC audiences and the Alex Higgins rivalry made snooker a British prime-time business.
World Championship purses rose with ratings while exhibitions filled the calendar. Steve Davis became the first player whose annual income looked like a mainstream UK sports star's.
Hendry dominance 1990–1999
Stephen Hendry's seven Worlds coincided with rising ranking-event money.
The 1990s professional circuit thickened. Hendry's prize-money leadership and Jimmy White's popularity premiums showed results and personality could both pay.
China & O'Sullivan 2000–2016
Chinese venues and Ronnie's fame multiplied what a season could earn beyond the Crucible.
Ding Junhui's domestic commercial value and O'Sullivan's global draw pushed totals past anything the 1980s BBC era paid, even when ranking prize money alone looked smaller than golf or tennis.
Modern tour purse 2017–present
Judd Trump and peers cleared multimillion seasons from a denser world ranking calendar.
More televised ranking events, Saudi and Far East promotions, and sustained Chinese demand kept top earners in the low-to-mid single-digit millions USD.
