Small Business Saturday is an American shopping holiday created by American Express, held on the Saturday after Thanksgiving during one of the busiest shopping periods of the year. First celebrated on November 27, 2010, it is a counterpart to Black Friday and Cyber Monday, which feature big box retail and e-commerce stores respectively. By contrast, Small Business Saturday encourages holiday shoppers to patronize brick and mortar businesses that are small and local.

In 2010 the holiday was promoted by American Express via a nationwide radio and television advertising campaign. That year Amex bought advertising inventory on Facebook, which it in turn gave to its small merchant account holders, and also gave rebates to new customers to promote the event.

American Express publicized the initiative using social media, advertising, and public relations. At least 41 [1] local politicians and many small business groups in the United States issued proclamations concerning the campaign, which generated more than one million Facebook "like" registrations and nearly 30,000 tweets under the Twitter hashtags #smallbusinesssaturday (which had existed since early 2010) and #smallbizsaturday.[2]

A small business, also called a mom and pop store by some in the United States, is a business that is privately owned and operated, with a small number of employees and relatively low volume of sales. Small businesses are normally privately owned corporations, partnerships, or sole proprietorships. The legal definition of "small" varies by country and by industry, ranging from fewer than 15 employees under the Australian Fair Work Act 2009, 50 employees in the European Union,[2] and fewer than 500 employees to qualify for many U.S. Small Business Administration programs. Small businesses can also be classified according to other methods such as sales, assets, or net profits.

Small businesses are common in many countries, depending on the economic system in operation. Typical examples include: convenience stores, other small shops (such as a bakery or delicatessen), hairdressers, tradesmen, lawyers, accountants, restaurants, guest houses, photographers, small-scale manufacturing, and online business, such as web design and programming, etc.
