Also, Sweden was the first European country that was connected to the U.S. Internet, or more specifically to NSFNET [1][2]. This was because the adoption of TCP/IP protocols for wide area networks came earlier in Sweden than in other parts of Europe, for various serendipitous reasons. A funny anecdote is that Switzerland could have beat Sweden to be connected first, but they were delayed because they had to renumber all their networks at CERN that were already using TCP/IP.

Initially it was just non-commercial Internet for academic institutions, but lots of students were exposed to the technology and the infrastructure early on.
