Based on this observation, retailers began to offer attractive deals with the idea of getting a larger share of that first round of holiday shopping. To meet the competition, many stores began to offer special deals available only in the morning (to get the shopper first and take that person out of the market before they shopped other stores).
Now Black Friday is part of the US culture with aggressive retailers offering deep discounts on popular items starting as early as midnight on Thanksgiving (and in some cases earlier ... trying to extend Black Friday into more than 24 hours)
The Internet has added a new twist to Black Friday, as many shoppers no longer have to wait for the Thursday newspaper (and other advertising) to find out the deals and plan their shopping. Now, there are many places on the Internet to find out the deals, each year offering that information earlier and earlier in advance of Black Friday.
Some of those sites include:
Based on the success of Black Friday, “spin-off” promotions have been created:
Small Business Saturday - the Saturday following Black Friday; developed by American Express to encourage holiday shoppers to patronize small and local retailers (http://www.sba.gov/saturday, https://www.americanexpress.com/us/small-business/Shop-Small/)
Cyber Monday - the Monday following Black Friday, created to persuade people to shop online (http://www.cybermonday.com, http://www.cybermonday2012.com/)
NOTE: along with the aggregators listed above, many of the large retailers also have their Black Friday and Cyber Monday deals listed on their own websites
