Token Ring) LANs resulting in the capture of a much larger market share." These conclusions were largely based on assumptions, at the time, that growth in the marketplace will come largely in LANs based on international standards In 1987 it was said, "throughout the 1990s we should anticipate that there will be a growth in 802.3 Ethernet) and 802.5

Even though the earliest LANs were of this genre, by 1989 it appeared that they were on the way out. We will take a close look at peer-to-peer LANs at a deeper level in some future posts By 1992, however, new life had been breathed into peer-to-peer networking by both Novell and Microsoft, along with the popularity of Artisoft's LANtastic.

The LAN: A History of Network Operating Systems Part 10
