First ARPANET Message

On October 29, 1969, Charley Kline at UCLA sent the first message over ARPANET to Bill Duvall at the Stanford Research Institute, intending to type 'LOGIN' but crashing the system after only 'LO'. This event marked the first host-to-host communication on the precursor network to the modern internet, demonstrating that packet-switched networking between geographically separated computers was feasible.

1970s

1971-10-01 Key

First Email Program

Ray Tomlinson of BBN Technologies sent the first network email between two machines on ARPANET and chose the '@' symbol to separate the user name from the host name, establishing the address format still in use today. His program SNDMSG/READMAIL was the first implementation of email as a store-and-forward messaging system across a network, laying the foundation for all subsequent email protocols including SMTP, POP3, and IMAP.

1973-01-01 Key

TCP/IP Concept Paper

Vint Cerf and Bob Kahn published 'A Protocol for Packet Network Intercommunication,' introducing the foundational concepts of TCP/IP — a layered, end-to-end, packet-switched networking architecture designed to interconnect heterogeneous networks. This paper introduced the concept of a 'gateway' (later called a router) and the principles of internetworking that underpin the entire modern internet.

1978-06-01

First Spam Email

Gary Thuerk of Digital Equipment Corporation sent an unsolicited commercial message to approximately 400 ARPANET users advertising DEC's new DECSYSTEM-20 computers, making it the first documented instance of email spam. The message provoked strong negative reactions from recipients and foreshadowed the spam problem that would eventually consume a majority of all internet email traffic.

1980s

1981-09-01 Key

TCP/IP Specification (RFC 791 & 793)

The Internet Protocol version 4 (RFC 791) and Transmission Control Protocol (RFC 793) were formally published, providing the definitive specifications for the two core protocols of the internet suite. RFC 791 defined the 32-bit IPv4 address space, packet fragmentation, and best-effort delivery, while RFC 793 defined the reliable, connection-oriented TCP segment format, three-way handshake, and flow control.

ARPANET Flag Day — Switch to TCP/IP

On January 1, 1983, ARPANET completed its mandatory cutover from the older NCP (Network Control Program) protocol to TCP/IP, a transition known as 'Flag Day.' This single coordinated switch — requiring all hosts to upgrade simultaneously — established TCP/IP as the universal protocol suite for internetworking and is considered the true birth date of the modern internet.

1983-11-01 Key

DNS Designed (RFC 882 & 883)

Paul Mockapetris published RFC 882 and RFC 883 (later superseded by RFC 1034 and 1035), introducing the Domain Name System as a hierarchical, distributed database to replace the single HOSTS.TXT file that had been manually distributed to all ARPANET hosts. DNS decentralized name resolution, enabled the internet to scale to billions of hosts, and introduced concepts such as zones, authoritative servers, and recursive resolution that remain in use today.

1984-01-01 Key

NSFNET Established

The National Science Foundation Network (NSFNET) was established to connect five supercomputer centers across the United States, initially at 56 Kbps and later upgraded to T1 (1.544 Mbps) and T3 (45 Mbps) speeds. NSFNET became the backbone of the civilian internet throughout the late 1980s and early 1990s, connecting universities and research institutions until its decommissioning in 1995 when commercial internet providers took over backbone routing.
