Market definition is a core concept of competition law in the European Union, the United States and Brazil. The present contribution first surveys the general approach to market delineation in these three jurisdictions. Against this background, it then embarks on a discussion of market definition in digital markets in the EU, US and Brazil, with a particular focus on multi-sided markets, zero-price services and the concept of digital ecosystems. It closes with some comparative remarks and an outlook.
