Black Friday 2010

Many merchants objected to the use of a negative term to refer to one of the most important shopping days in the year. By the early 1980s, an alternative theory began to be circulated: that retailers traditionally operated at a financial loss for most of the year (January through November) and made their profit during the holiday season, beginning on the day after Thanksgiving. When this would be recorded in the financial records, once-common accounting practices would use red ink to show negative amounts and black ink to show positive amounts. Black Friday, under this theory, is the beginning of the period where retailers would no longer have losses (the red) and instead take in the year's profits (the black). The earliest known use, which like the 1966 example above was found by Bonnie Taylor-Blake of the American Dialect Society, is from 1981, again from Philadelphia, and presents the "black ink" theory as one of several competing possibilities:
If the day is the year's biggest for retailers, why is it called Black Friday? Because it is a day retailers make profits -- black ink, said Grace McFeeley of Cherry Hill Mall. "I think it came from the media," said William Timmons of Strawbridge & Clothier. "It's the employees, we're the ones who call it Black Friday," said Belle Stephens of Moorestown Mall. "We work extra hard. It's a long hard day for the employees."
The Christmas shopping season is of enormous importance to American retailers and, while most retailers intend to and actually do make profits during every quarter of the year, some retailers are so dependent on the Christmas shopping season that the quarter including Christmas produces all the year's profits and compensates for losses from other quarters.
