In 2022, CESP accompanied Médiamétrie in the realization of the project of bringing together the TV and Internet establishment surveys, Home Devices and OUI-TSM. This project for a single establishment survey is rooted in the cross-media context and will allow an increase of the sample size of the establishment survey of the Global Internet Audience study, in accordance with the recommendations of CESP Scientific Committee. After this conclusive test, Médiamétrie officially set up this unique etablishment survey in January 2023.
