The world's first internet transmission occurred on October 29, 1969. At least, that's what some people believe. Others say the more important moment arrived eight years later, when a repurposed delivery van equipped with a wireless transmitter sent a message from San Francisco to Norway and back to California by way of satellite.
The date was November 22, 1977, and no one seems to remember what message was sent - or even who was in the van. But they do remember how it was sent. This marked the first time the TCP/IP protocol - designed by Vint Cerf and Bob Kahn (pictured above) and the same protocol that underpins today's internet - was used to send information across not one. not two, but three independent computer networks.
