In modern English, a casino is a facility which houses and accommodates certain types of gambling activities. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships or other tourist attractions. There is much debate over whether or not the social and economic consequences of casino gambling outweigh the initial revenue that may be generated.
In the United States, many states are grappling with high unemployment and budget deficits and are now turning to legalizing casinos, often in places that are not tourist destinations. Some casinos are also known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events. Use of the word in the past, and modern use in some countries, does not necessarily involve gambling.

The Casinos was a nine-member doo-wop group from Cincinnati, Ohio, led by Gene Hughes. They are best-known for their John D. Loudermilk-penned song "Then You Can Tell Me Goodbye," which hit number 6 on the Billboard Hot 100 chart in 1967, well after the end of the doo-wop era.
