Cyber Monday is a marketing term for e-commerce transactions on the Monday after Thanksgiving in the United States. It was created by retailers to encourage people to shop online. The term was coined by Ellen Davis of the National Retail Federation and Scott Silverman, and made its debut on November 28, 2005, in a Shop.org press release entitled "'Cyber Monday' Quickly Becoming One of the Biggest Online Shopping Days of the Year". Cyber Monday takes place the Monday after Thanksgiving; the date falls between November 26 and December 2, depending on the year.
Cyber Monday has become the online equivalent to Black Friday and offers a way for smaller retail websites to compete with larger chains. Since its inception, it has become an international marketing term used by online retailers around the world.
According to the Shop.org/Bizrate Research 2005 eHoliday Mood Study, "77 percent of online retailers said that their sales increased substantially on the Monday after Thanksgiving, a trend that is driving serious online discounts and promotions on Cyber Monday this year (2005)".

The Cyber Monday on November 30, 2020 was the biggest online shopping day in U.S. history with a total of $10.7 billion in online spending.
The term "Cyber Monday" was coined by Ellen Davis, and was first used within the ecommerce community during the 2005 holiday season. 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). Retailers also noted the most significant shopping period was December 5 through 15 of the previous year. In late November 2005, The New York Times reported: "The name Cyber Monday grew out of the observation that millions of otherwise productive working Americans, fresh off a Thanksgiving weekend of window shopping, were returning to high-speed Internet connections at work Monday and buying what they liked." At the time, a lot of people had slow Internet at home. The idea for having such a holiday was created by Tony Valado, in 2003 while working at 1800Flowers.com, and coined "White Wednesday" to be the day before Thanksgiving for online retailers.
