A system built on Médiamétrie’s TV and Internet measurements

4-screen TV/Video and 3-screen Video audience results come from reconciling several data sources in France:

Mediametrie//NetRatings’ computer video panel for the computer video audience
The reference panel for measuring television, Médiamat, for the TV audience
Médiamétrie’s site-centric measurement, eStat Streaming, across all internet screens
The Google and Médiamétrie single source panel (TV and internet panel) for calculating contributions between different screens
