The second half of the 20th century is often described by press photography as a "crisis" or the "end of press photography". The reasons for this were amongst other things changes in the media landscape, in the sales channels of media products or in photo technology. This publication examines how the St.Gallen Pressebüro Kühne Künzler responds to these changes over a period of more than 50 years. The unique position of the press office as regards information given its excellent archives enabled the inclusion not only of picture and written sources but also objects in the fields of research company, market and product. This meant that various aspects of the history of photography, the history of technology, local history, economics but also journalism studies and media sciences could be addressed.
