To ensure compatibility, the IEEE 802.3 standards had to address the needs of Layer 1 and the lower portion of Layer 2 of the OSI model. The IEEE wanted to make sure that its standards were compatible with those of the International Standards Organization (ISO) and OSI model. These standards start with the number 802. In 1985, the Institute of Electrical and Electronics Engineers (IEEE) standards committee for Local and Metropolitan Networks published standards for LANs. The first products that were developed from the Ethernet standard were sold in the early 1980s. Metcalfe wanted Ethernet to be a shared standard from which everyone could benefit, and therefore it was released as an open standard. The first Ethernet standard was published in 1980 by a consortium of Digital Equipment Corporation, Intel, and Xerox (DIX). Robert Metcalfe and his coworkers at Xerox designed it more than thirty years ago. The first LAN in the world was the original version of Ethernet.
