Online advertising

The CNMC has started a market study on online advertising. The first stage has been a public consultation (aiming at collecting the views of the main stakeholders in this sector), which was open from April 25th to May 24th 2019.

Below you may find the results of the public consultation, including all the individual submissions (you may also find a Word file with the complete form which was the object of the public consultation, just for information purposes). In this post in CNMC’s blog you can find an aggregated summary of the contributions.

The CNMC continues preparing its market study and will go on informing on the next steps. Should you wish to provide additional information to the CNMC regarding this study, you could do so by sending an e-mail to with the subject “Study on online advertising”.
