what is the origin of black friday sale
Black Friday (shopping) The earliest evidence of the phrase Black Friday applied to the day after Thanksgiving in a shopping context suggests that the term originated in Philadelphia, where it was used to describe the heavy and disruptive pedestrian and vehicle traffic that would occur on the day after Thanksgiving. This usage dates to at least 1961. More than twenty years later, as the phrase became more widespread, a popular explanation became that this day represented the point in the year when retailers begin to turn a profit, thus going from being "in the red" to being "in the black".[7][8][9][10]
Supermarket It has been determined that the first true supermarket in the United States was opened by a former Kroger employee, Michael J. Cullen, on 4 August 1930, inside a 6,000-square-foot (560Â m2) former garage in Jamaica, Queens in New York City.[13] The store, King Kullen, operated under the slogan "Pile it high. Sell it low." At the time of Cullen's death in 1936, there were seventeen King Kullen stores in operation. Although Saunders had brought the world self-service, uniform stores and nationwide marketing, Cullen built on this idea by adding separate food departments, selling large volumes of food at discount prices and adding a parking lot.
