A one stop shop, one stop store or one stop source is a business or office where multiple services are offered; i.e., customers can get all they need in just "one stop." The term originated in the United States in the late 1920s or early 1930s1 to describe a business model offering customers the convenience of having multiple needs met in one location, instead of having to "drive all over town" to attain related services at different stores. The phrase is now used as slang to describe everything from Web sites to TV shows where people can find most of what they need, including information, in one place.
"The term originated in the USA in the late 1920s, early 1930s. The earliest I can find is this advert for a car repairer, from The Lincoln Star, Lincoln, Nebraska, July 1930. They managed to sum up what the term was all about in their strapline - 'Have it all done in one place. Save your time. Save your money'."
