Electronic commerce originated from electronic data transmission during the Berlin airlift in 1948. In the 1960s, early attempts were made to develop common electronic data formats, mainly used for industry transactions. It was not until the late 1970s that national electronic data exchange standards began to develop. E-commerce is defined as business transactions that take place over telecommunications networks, especially the Internet. Key drivers of e-commerce include technological advances, social factors, economic changes, and political environments. E-commerce impacts areas like marketing, computer science, finance, and operations management.
