2^nd September, 1969 marks the date upon which the first bits of data passed from one computer to a second, using a simple piece of grey cable and an Interface Message Processor.

The computers were 15 feet apart.

It was not until 29^th October that data was passed over a larger distance. From Professor Leonard Kleinrock's lab at the University of California, Los Angeles, an attempt was made to connect to a system located at the Stanford Research Institute, where Charley S. Kline got as far as LO (for LOGIN) and his remote system crashed!
