History of online shopping
One of the earliest forms of trade conducted online was IBM's online transaction processing (OLTP) developed in the 1960s, which allowed the processing of financial transactions in real-time. The computerized ticket reservation system developed for American Airlines called Semi-Automatic Business Research Environment (SABRE) was one of its applications. There, computer terminals located in different travel agencies were linked to a large IBM mainframe computer, which processed transactions simultaneously and coordinated them so that all travel agents had access to the same information at the same time. At some point between 1971 and 1972, students at Stanford and MIT used the internet precursor ARPANET to make a deal to exchange marijuana, but the interaction does not qualify as e-commerce because no money was transferred online.
