Who invented Internet shopping?

Tesco is recorded as having provided the world's first operational Business-to-Consumer (B2C) teleshopping system in 1984. Prior to this, ecommerce already existed in the form of Business-to-Business (B2B) services, but these services were not provided for consumers (ie- "home shoppers").

Tesco's online shopping system was made possible by systems developed by Rediffusion Computers, and invented by the company's founder, Michael Aldrich, in 1979.
