Abuse of dominance

Undertaking(s) concerned:

Nielsen Közönségmérés Kft.

Short description:

The GVH investigated the market of softwares used to analyse television audience measurement data in order to find out whether Nielsen abused its dominant position or not by tying and granting rebates on the one hand and refusing to give licence and access to its database on the other hand.


The GVH accepted the commitments offered by Nielsen, pursuant to which in the future it will set the prices of its databases and of the related discounts transparently; it will elaborate a new package-structure and it will enable its customers to entrust third parties with the management and processing of the databases.
