"The busiest shopping and traffic day of the year"
New York, U.S.
Use of the phrase spread slowly, first appearing in The New York Times on November 29, 1975, in which it still refers specifically to "the busiest shopping and traffic day of the year" in Philadelphia. Although it soon became more widespread, The Philadelphia Inquirer reported in 1985 that retailers in Cincinnati and Los Angeles were still unaware of the term.
