First message sent over ARPANET

The first message sent over ARPANET, the precursor to the internet, occurred on October 29, 1969. It was a test to see if a computer could communicate with another remotely located computer. The researchers attempted to send the word "LOGIN," but the system crashed after transmitting "LO." This marked the first time a message was successfully sent between two computers over a network, demonstrating the potential for digital communication and laying the groundwork for modern computer networking.
