This dissertation was written as part of the LLM in Transnational and European Commercial Law, Mediation, Arbitration and Energy Law at the International Hellenic University. Access and collection of users; data is critical in the online marketing business. It has been argued that the accumulation of data that arises from concentrations, increases the likelihood of successful companies becoming dominant over their respective field. This raises the chance of them abusing their position in order to harm competition. This dissertation intends to contribute to the important discussion on the interface between data gathering and competition law in the context of the European Union. The paper aims at mapping and assessing various interplay possibilities between personal data and competition law. There are also references to the major cases that the European Commission has examined like Facebook - WhatsApp, Google - DoubleClick, TomTom -Tele Atlas, IMS Health case and Microsoft - Yahoo mergers. The assumption is that data accumulation has the potential to alter the dynamics of competition in a relevant market. In my opinion it is extremely possible under certain circumstances. Nevertheless, the merger cases that were investigated from a competition standpoint, show that many factors should be taken into account before reaching any conclusions.
