Somewhere along the way, Black Friday made the giant leap from congested streets and crowded stores to fevered shoppers fist-fighting over parking spaces and pepper-spraying each other as they tussle for the lasf Tickle Me Elmo. When did Black Friday become the feeding frenzy,over-the-top shopping event it is today? That would be in the 2000s, when Black Friday was officially designated the biggest shopping day of the year. Until then, that title had gone to the Saturday before Christmas. Yet as more and more retailers started touting "can't miss" post-Thanksgiving sales and the Black Friday discounts grew deeper and deeper, American consumers could no longer resist the pull of this magical shopping day. Retailers may spend an entire year planning their Black Friday sales. They use the day as an opportunity to offer rock-bottom prices on overstock inventory and to offer doorbusters and discounts on seasonal items, such as holiday decorations and typical holiday gifts. Retailers also offer significant discounts on big-ticket items and top-selling brands of TVs, smart devices and other electronics, luring customers in hope that, once inside, they will purchase higher-margin goods. The contents of Black Friday advertisement are often so highly anticipated that retailers go to great lengths to ensure that they don't leak out publically beforehand.
