Turid Borgen obtained har PhD in journalism from Stockholm University in May 2017. Her thesis has the title "Between societal mission and market demands. A study of the role of editors-in-chief in leading Norwegian and Swedish media companies from 1985 to 2015". The dissertation analyses changes in the role of editors-in-chief in ten leading Norwegian and Swedish media houses – today owned by either Bonnier or Schibsted – in light of the potential tensions between journalistic ideals and market demands. This duality is studied over a period of 30 years, from 1985 to 2015. The most defining changes in the structural framework under which editors-in-chief work are the ongoing technological revolution, the transformation from an analogue into a digital society, and structural, economic changes related to this development.
