After studying Anglistics and American studies (1967/68) at the Wagner College in New York and Germanistics and theatre studies in Vienna from 1968 - which he did not complete - Thurnher became a member of the editorial collective of Falter in 1977, member of the editorial collective of the Viennese city newspaper Falter founded and published by Walter Kienreich [de] and (since June 2012) continues to be its publisher as well as its editor-in-chief alongside Florian Klenk [de].
Since 1970 he has been active as a freelance author, actor and stage musician at the theatre; in 1972 he wrote the play Stoned Vienna together with Heinz Rudolf Unger [de].
[1][2] Thurnher is a critic of the Austrian print media landscape, which is dominated by the Kronen Zeitung and the glossy magazines of the NEWS group.
He concluded his editorials in the Falter, every week for twenty years, in the style of Cato's Ceterum censeo Carthaginem esse delendam with the sentence: For the rest, I am of the opinion that the Mediamil complex must be smashed.
Mediamil is a word combination created by Thurnher from Mediaprint [de] and the magazines Format and Profil from the NEWS group.
