The recent high-profile M&A transactions indigital Internet markets raised the question on the potential influence on the competition merger andacquiring control over big data. Indeed, companies can involve advanced computer technologies tocoordinate business practices, impose abusive conditions for consumers, applying compelling marketpower to set higher prices or even possible closing the market for new market-players.
