Grand Prix

The tournament was created in 1982 as the Professional Players Tournament by the World Professional Billiards and Snooker Association, in order to provide another ranking event. Ray Reardon beat Jimmy White by 10 frames to 5 in the final to win the first prize of £5,000.

In 1984 Rothmans started sponsoring the tournament, changing its name to the Grand Prix, and moved its venue to the Hexagon Theatre in Reading. The tournament has had various sponsors and venues since. Previous sponsors include LG Electronics, who took over in 2001 and changed the tournament's name to the LG Cup. After LG withdrew their sponsorship, the Grand Prix name was revived for 2004 and was sponsored by totesport. Between 2006 and 2008 the event was sponsored by Royal London Watches.

The tournament was played at the Guild hall in 1998, at the start of the snooker season, until 2005 (moving once to Telford in 2000). Prize money for 2005 totalled £400,000, with the winner receiving £60,000.

In its original form, the tournament had a flatter structure than most tournaments, with the top 32 players all coming in at the last 64 stage (in other tournaments there are only 16 players left when the players ranked 17–32 come in, and then the 16 winners of those matches face the top 16).

These facts made it more common to see surprise results than in most other tournaments, with players such as Dominic Dale, Marco Fu, Euan Henderson and Dave Harold all surprise finalists at the time. A player from outside the top 16 has reached the final roughly half the times the contest has been played. Few of those have become consistent stars, although Stephen Hendry and John Higgins took their first ranking titles in the event. In addition, over the years, many top 16 players were eliminated in the early stages of the contest. Taking the 1996 event as an extreme case, thirteen of the top sixteen seeds failed to reach the quarter final stages, and the semi-finals featured one match between two top 16 players (Mark Williams and John Parrott) and another between two unseeded players (Euan Henderson and Mark Bennett); with Bennett and Henderson respectively winning the first two quarter final matches, a surprise finalist was guaranteed before the quarter finals had been completed.

The event moved to Scotland at the A.E.C.C. in Aberdeen for 2006, and introduced a brand new format. Players were split into groups (8 groups of 8 in qualifying, 8 groups of 6 in the final stages) and played every other player in their group once. The top 2 players progressed; the last 16 and onwards were played as a straight knock-out.

This resulted in several surprise results. Little-known players such as Ben Woollaston, Jamie Jones and Issara Kachaiwong made it through qualifying, while stars such as Graeme Dott, Stephen Hendry and Shaun Murphy failed to clear their groups.

The format was slightly tweaked for 2007, after complaints (notably from Dennis Taylor) that the system was too random. Matches increased in length from best-of-5 to best-of-7, to give the better player more chance to win. The main tie-breaker for players level on wins was changed, with frame difference now taking precedence over results between the players who are level on points. Notably, under the 2007 format, 2006 runner-up Jamie Cope would have been eliminated in the groups, as he defeated third-placed Michael Holt but had an inferior frame-difference.

The 2007 event saw fewer surprises, although 2006 World Champion Graeme Dott, 1997 World Champion Ken Doherty, defending champion Neil Robertson, seven-time World Champion Stephen Hendry, six-time World Champion Steve Davis, twice World Champion Mark Williams and 2007 World Championship finalist Mark Selby were all eliminated in the groups. The format was not continued for 2008, due to dwindling ticket sales in the early rounds.

For 2008, the event moved to the Scottish Exhibition and Conference Centre (SECC) in Glasgow. It went back to a knock-out format with no round-robin. The last 16 and beyond however was played using a FA Cup-style draw, rather than automatically pitching higher ranked players (or their conquerors) against lower-ranked players. In 2009, the event was held in Glasgow, but at another venue, the Kelvin Hall.

Following Barry Hearn's takeover of the World Professional Billiards and Snooker Association, the Grand Prix was reformatted and renamed to World Open. The event gave a chance for amateurs to play alongside professionals. The amateurs had to win 3 matches to qualify for the main draw. On 9 January 2012 it was announced, that the World Open would be held in the next five years in Haikou on the Hainan Island. In November 2014, it was announced that the tournament will not be held in the 2014/2015 season after the contract with the promoter was not renewed and a new venue was not found in time. But the intention is to bring the event back in the 2015/2016 season.
