The 1985 World Snooker Championship final, also known as the black-ball final, was played on the weekend of 27–28 April 1985 at the Crucible Theatre in Sheffield, England. The final of the 1985 World Snooker Championship was between defending world champion Steve Davis and 1979 runner-up Dennis Taylor. It was Davis's fourth appearance in a final and Taylor's second. The best-of-35-frame match was split into four sessions. Davis won every frame in the first session to lead 7–0 but only led 9–7 and 13–11 after the second and third sessions. Until the match was over, Taylor was never ahead in frames but had tied the contest three times at 11–11, 15–15 and 17–17. The deciding frame culminated in a number of shots on the final black ball. After both players had failed to pot it several times, Taylor potted the black to win his only world championship. Media outlets reported this as a major shock: Davis had been widely predicted to win the match, having lifted three of the previous four world championship titles.
The final took place during the eighth year of the BBC's daily coverage of the championship and reached a climax in the early hours of Monday 29 April. It was viewed by 18.5 million people in the United Kingdom, which as of 2024[update] remains a record viewing figure for BBC2, and as of 2024[update] is still the record for a post-midnight audience for any British television channel. The total match time of 14 hours and 50 minutes is the longest ever recorded for a best-of-35-frames match. It is the only final at this venue to contain no century breaks.
The final is one of the most famous matches in snooker history and part of the reason for the surge in the sport's popularity in the 1980s and 1990s. Two hour-long BBC documentaries, When Snooker Ruled the World from 2002 and Davis v Taylor: The '85 Black Ball Final made in 2010, commemorated the event. The final frame was released in full on home video as "The Greatest Snooker Final of All Time". The post-match single-word responses to David Vine from Davis would later be used as a basis for a recurring caricature of him in the television show Spitting Image.
