Media Usage

How is your user base segmented? What are their motives for using your media? How long will your users, readers, viewers or listen­ers stay engaged? These are questions that can be answered using a variety of methods.

Media Impact

What effects does your media presence have? What are the reactions to your medium? The ef­fects on people or the consequences for society and its areas can be re­searched, e.g. politics or economy.

About me

SandhöferAfter studying journalism with a focus on empirical com­mu­nication research at the Free University of Berlin, working as a re­search assistant at the market research insti­tute forsa and in the media research depart­ment of RTL, I switched to program research at ProSieben in Unter­föhring in the Greater Munich area. I soon took on new responsi­bili­ties within the group as the manager of Research New Media, which encompassed all media research activi­ties for online and tele­text of the ProSieben, SAT.1, kabel eins and N24 networks.

Before leaving Pro­Sie­ben­Sat.1 Media SE, I also represented the group in various media research committees, such as the Working Group Online Research (agof), the Working Group Media Analysis (agma) or the AGF Video Research. I was also able to share my experiences in industry associations such as VAUNET - Association of Private Media or the German Association for the Digital Economy (BVDW).

As "Elected Market Researcher" for the Internet media genre, I was a member of agma's Technical Commission (German only) until the end of 2022 and worked on agof's Technical Commission/Working Group Methodological Issues. Which was - as previously stated on the agof website - "responsible for the clarification of cross-study-model issues as well as methodological challenges and prepared possible study extensions".

I am enrolled as a "market researcher BVM" in the register of qualified researcher of the Professional Associ­ation of German Market and Social Re­searcher (BVM) and thus commit myself to compliance with qual­ity standards, profes­sional rules and data protection. Marktforscher BVM
