On 1 January 1924 the City of Graz and Kienreichs Anzeigen Vermittlungsgesellschaft m.b.H. founded Ankünder Steiermärkische Ankündigungs GesmbH as a company with its registered office in Graz.
At that time, the company’s object was to carry out all forms of advertising, which, in the 1920s, essentially meant advertising with small posters.
The use of large-format posters had begun by the early 1950s, starting in the USA.
Since 1975, buses have been used as an advertising medium in Graz.
On 1 January 1985, Ankünder was taken over by Grazer Stadtwerke AG.
