Cyber Monday is an e-commerce term referring to the Monday following the U.S. Thanksgiving weekend. As brick-and-mortar stores do with Black Friday, online retailers usually offer special promotions, discounts, and sales on this day. Meanwhile, traditional retailers offer exclusive, website-only deals.
According to Scott Silverman, the head of Shop.org, the term was coined based on 2004 research showing "one of the biggest online shopping days of the year" was the Monday after Thanksgiving (12th-biggest day historically).
Cyber Monday was first used in 2005 by the National Retail Federation to encourage people to shop online. Cyber Monday is often considered to be the online shopping equivalent of Black Friday, which dates back to at least the 1950s and has historically been one of the busiest shopping days of the year.
