Pocket billiards

Pocket billiards, most commonly referred to as pool, is the general term for a family of games played on a specific class of billiards table, having 6 receptacles called pockets (or "holes") along the rails, in which balls are deposited as the main goal of play. Cue sports that are played on pocketless tables are generally referred to as carom billiards.

Outside the cue sports industry, pocket billiards is almost exclusively referred to as "pool", due to a perhaps unfortunate association with the "poolrooms" where gamblers "pooled" their money to bet remotely ("off-track") on horse races. Because these venues often provided billiard tables, the term "pool" became synonymous with billiards. Though the original "pool" game was played on a pocketless table, the name stuck to pocket billiards as it gained in popularity. Though the traditional view of billiards as a refined and noble pastime did not blend well with the low-class connotations of gambling, the billiards industry's attempts to distance itself from the term "pool" beginning in the late 19th century were largely unsuccessful.

There are hundreds of pocket billiards games. Some of the more well known include eight-ball, nine-ball, straight pool, and one-pocket. The game of snooker is played on a table with pockets but is considered to be its own cue sport and is governed internationally by the World Professional Billiards and Snooker Association/World Snooker Association (professional) and International Billiards and Snooker Federation (amateur). There are also hybrid games combining aspects of both pocket and carom billiards, such as English billiards, American four-ball billiards, cowboy pool and bottle pool.Pocket billiards is more popular than carom billiards in most countries of the world.[citation needed] Carom billiard games thrive in Asia, Europe and Latin America, but pool (especially in the form of nine-ball and eight-ball) and snooker are gradually taking over as the most widely played cue games.

As a competitive sport, pocket billiards is governed internationally by the World Pool-Billiard Association (WPA), which has national affiliates such as the US Billiard Congress of America (BCA), and which represents pocket billiards in the World Confederation of Billiard Sports which in turn represents all forms of cue sports in the International Olympic Committee.
