Invention is rarely the isolated product of a lone scientist or engineer. Instead, every significant technology in the modern world is the product of a long history of numerous people and events. One of our most modern inventions, the Internet, is itself the result of decades of work and innovation by thousands of people who may have never dreamed of the possibility or potential of a global network.

One interesting and influential ancestor in the history of the Internet is radar. Hundreds of the best scientists and engineers in Britain and the U.S. worked during World War Two to develop radar systems to help them to defeat the Axis powers. Electronics technology was pushed to new heights to make the signals stronger, and early computing machines were developed to process the complex radar messages.
