Today in 1940, in a demonstration to the American Mathematical Society conference at Dartmouth College, George Stibitz of AT&T used a teletype terminal to send commands to the Complex Number Calculator in New York over telegraph lines.
It was the first demonstration of remote computation. In 2022, worldwide revenue for the public cloud services market totaled $545.8 billion, an increase of 22.9% over 2021, according to IDC. And more than 5 billion people worldwide engage in remote access to computation, communications, information, and entertainment.
