Performance of a programme over 4 screens

Bon à savoir

Each day “Focus Emission” provides 4-screen results by programme

Since April 2016, Médiamétrie has offered a service called “Focus Emission”, the audience for TV programmes across 4 screens: television, computer, smartphone and tablet. Every day, clients subscribing to the measurement can learn for each programme on channels that have marked their content with the eStat Streaming tag, the average number of viewers per screen and per mode of consumption (live, time-shifted or catch-up). Focus Emission is available via Restit TV, the Médiamat results reporting interface. Since 27 September 2016, these results have been shared with all Médiamat clients.
