GOSIP
Government OSI Profile — governments' attempt to mandate the OSI protocols into existence and retire TCP/IP through procurement rules.
In the 1980s most governments and telecom operators took it for granted that future networks would run on OSI, not on the American research network's makeshift TCP/IP. The US published its GOSIP as FIPS 146 in 1988, and from 1990 federal agencies were supposed to buy OSI-compliant equipment. Britain and several other countries had profiles of their own. Vendors promised OSI support in every bid.
The trouble was that TCP/IP already worked, was free to read and shipped with every BSD install, while OSI products were expensive, late and rarely interoperated. Agencies duly bought OSI on paper and ran TCP/IP in practice. In 1995 the revised standard accepted the internet protocols, which amounted to surrender. The protocol wars weren't settled by a decree but by whatever was already in production.
