E-commerce refers to the purchase and sale of goods and/or services via electronic channels such as the Internet. E-commerce was first introduced in the 1960s via an electronic data interchange (EDI) on value-added networks (VANs). The medium grew with the increased availability of Internet access and the advent of popular online sellers in the 1990s and early 2000s. Amazon began operating as a book-shipping business in Jeff Bezos' garage in 1995. EBay, which enables consumers to sell to each other online, introduced online auctions in 1995 and exploded with the 1997 Beanie Babies frenzy. Like any digital technology or consumer-based purchasing market, e-commerce has evolved over the years. As mobile devices became more popular, mobile commerce has become its own market. With the rise of sites like Facebook and Pinterest, social media has become an important driver of e-commerce. As of 2013, Facebook drove 85 percent of social media-originating sales on e-commerce platform Shopify, according to Pay mill.
