As such, he is taking over from Benoît Cassaigne, who is retiring but who will continue to work with Médiamétrie’s chairperson in an advisory capacity.
Commenting on the development, Yannick Carriou, chairman and CEO of Médiamétrie, said: “I thank Benoît Cassaigne very much for his work at Médiamétrie. Benoît has been a key player in media audience measurement innovation. To name just a few: hybrid measurement of landline internet in 2012, total internet measurement in 2015, integration of time-shifted audiences and then catch-up in television and, this year, outside the home in the Médiamat, as well as measurement of streaming radio and podcasts. Benoît Cassaigne has also greatly contributed to the development of Médiamétrie’s position as a neutral and independent trusted third party in the media and digital ecosystem”.
Rosanvallon will be supported by all the audience measurement directors at Médiamétrie including Laurence Deléchapt, who was previously director of the National Médiamat Department and who will take charge of Médiamétrie’s Television Department.
