 Most national EUnet affiliates or subsidiaries predated other commercial Internet offerings in the respective countries by many years.To completely understand the importance and history of EUnet, it is important to realize that until the early 1990s nearly every European country had a telecommunications monopoly with an incumbent national PTT, and that commercial and non-commercial provision of telecommunications services was prohibited or at least took place in a legal "grey zone".During the same period, as part of an industrial political strategy to stop US domination of future network technology, the EC embarked on efforts to promote OSI protocols, founding for example RARE and associated national "research" network operators (DFN, SURFnet, SWITCH to name a few).
