TOPIC: TCP in '73!
I love computer and Internet history. In terms of human or world history, computer history is exponentially "faster". Witness this...

"Bob Kahn and Vint Cerf presented their paper 'A Protocol for Packet Network Intercommunication' in September, 1973. The paper described a new protocol they called the Transmission-Control Protocol (TCP).
In 1978, the TCP protocol was split into two parts. One part was for dividing messages into datagrams, reassembling messages, and detecting errors. The other part was for routing and delivery of data. The protocol was named TCP/IP and subsequently became the standard for all Internet communication."

Within a mere 28 years, almost everyone in the industrialized world knows what TCP/IP means -- if not by definition, by popular use on the Internet. Isn't that AWESOME?!?
