The term e-commerce has its roots in the 1960s when electronic data interchange (EDI) systems began enabling business transactions to be conducted over long distances.
However the term gained widespread use in the 1990s with the advent of the World Wide Web. As online shopping and business transactions began to rise the term e-commerce was coined to describe these new online transactions.
