Norway have had at least half a dozen language reforms in parliament that dictate the written language, and so indirectly pronunciation.
E.g. the 1907 reform removed a lot of soft consonants in favour of harder ones (e.g. "løb" -> "løp", "kage" -> "kake").
Most of them, incidentally, reducing the similarity with Danish...
Fun fact: it was actually decided in Stortinget (the supreme legislature of Norway) in November 1950 and implemented in July 1951, as far as I know the only time a matter of how to pronounce something has been decided at that level.
