The National Media Research (NMO) is a comprehensive initiative that provides insight into the media behavior of the Dutch population. This research measures and reports on the collective reach of television, radio, print, and online media. NMO was created through a collaboration between four key media research organizations in the Netherlands: TV Research Foundation (SKO), National Listening Research (NLO), National Multimedia Research (NOM), and United Internet Exploiters (VINEX). The goal of NMO is to collect detailed information about how Dutch people consume various media, including viewing habits, listening patterns, reading behaviors, and internet activities. This data is of great importance to various parties in the media industry, such as broadcasters, advertisers, and media planners. To achieve this, NMO uses advanced research methods, including a panel of households equipped with special measuring equipment. Since August 2023, NMO has adjusted its methodology to better account for changing viewing patterns, now also incorporating delayed viewing in the final viewing figures.
