Pool and billiards developed as an indoor option to substitute for games such as croquet that were played on lawns.
[1] In North America in the 1950s and 1960s especially, pool halls in particular were perceived as a social ill by many, and laws were passed in many jurisdictions to set age limits at pool halls and restrict gambling and the sale of alcohol.
[2][3] The song "Trouble" in the 1957 hit musical The Music Man lampooned this prejudice (even contrasting carom billiards, requiring "judgement, brains, and maturity", versus pool, said to be a gateway to laziness, gambling, smoking and philandering).
[2] By the 2010s, with competition from a growing number of competing entertainment venues, as well as the availability of online gambling, revenue from the operation of billiard halls in the United States had declined significantly.
[7] Pool halls feature prominently in the novel and film The Hustler, and their sequel book and movie, The Color of Money, as well as other pool films such as Poolhall Junkies and Shooting Gallery.
