The digital economy is transforming economies and society globally. It is opening new markets  and enabling consumers to keep up with news, share creative content and connect with people  around the world. Technological developments, be they in relation to platforms, app stores, cloud  computing or artificial intelligence ("AI"), as well as related data and privacy issues, continue to  fuel the competition debate. Competitive dynamics and conduct of firms active in the digital  economy have raised some concerns among competition authorities. In some cases, competition  authorities have intervened to safeguard competition and innovation, which they fear may be  stifled by firms with market power. This has resulted in a growing number of merger reviews,  market studies and antitrust enforcement cases as well as several policy and legislative changes  in the competition field.
