- On May 22, 1973, Bob Metcalfe at Xerox PARC documented the invention of Ethernet in a memo, which described communication across different "ethers" - including cable, telephone, and radio - building on the ALOHAnet protocol.
- Bob Metcalfe, David Boggs, and Tat Lam built the first Ethernet prototype at 2.94 Mbps.
