Billiards historian Michael Ian Shamos in "The Illustrated Encyclopedia of Billiards" (1993), citing information provided by Charles C. Peterson (first president of the Billiard Association of America), and Steve Mizerak and Michael E. Panozzo in "Steve Mizerak's Complete Book of Pool" (1990), indicate that ascribing the phrase's origin to the game of eight ball results in an anachronism, the phrase being traceable to at least 1919, while the form of game that became "eight-ball" was not described by that name, and its rules were not published in any official rule book, until after 1940. The game that would ultimately be named "eight ball," after a physical 8 ball became part of play, was invented shortly after 1900. That precursor game was little known until it was popularized in 1925 under the name "B.B.C. Co. Pool" by the Brunswick-Balke-Collender Company, marketed by them with a special set of balls that did not have a numbered 8 ball, but rather came with a ball set consisting of seven of one color, seven of another, and an unnumbered black ball. Thus, multiple-time world champion Steve Mizerak explains that "behind the eight ball" cannot derive from the game of eight ball as "the phrase predates the game ... by at least 20 years."
