Online retail, also known as e-commerce, involves buying and selling products or services via the internet. It offers conveniences like being open 24/7 without barriers of time or distance, and allows for low operational costs and a global reach of customers without geographical limitations. The history of e-commerce began in the 1960s with electronic data interchange, and expanded in the following decades with innovations like online shopping concepts in the 1970s, software sellers using merchant accounts in the 1980s, and the creation of the world wide web and first web browser and server in 1990. Major online retailers like Amazon, eBay, and early internet adopters like Dell and Cisco further grew the industry in the 1990s.
