Towards the end of the summer of 1969 – a few weeks after the moon landings, a few days after Woodstock, and a month before the first broadcast of Monty Python’s Flying Circus – a large grey metal box was delivered to the office of Leonard Kleinrock, a professor at the University of California in Los Angeles. It was the same size and shape as a household refrigerator, and outwardly, at least, it had about as much charm. But Kleinrock was thrilled: a photograph from the time shows him standing beside it, in requisite late-60s brown tie and brown trousers, beaming like a proud father.
Had he tried to explain his excitement to anyone but his closest colleagues, they probably wouldn’t have understood. The few outsiders who knew of the box’s existence couldn’t even get its name right: it was an IMP, or ”interface message processor”, but the year before, when a Boston company had won the contract to build it, its local senator, Ted Kennedy, sent a telegram praising its ecumenical spirit in creating the first ”interfaith message processor”. Needless to say, though, the box that arrived outside Kleinrock’s office wasn’t a machine capable of fostering understanding among the great religions of the world. It was much more important than that.
