The document discusses SKO's efforts to integrate online video and TV ratings in the Netherlands. It describes a two-step process: 1) A census measurement of all online video streams and commercials across devices using tags. This provides exact viewership data. 2) An online panel to estimate reach and demographic profiles and link online and TV viewing behavior at both household and individual levels. The goal is to provide a holistic view of the Dutch online video audience across platforms through a hybrid model combining census and panel data.
