The Digital Markets Act (DMA) is a European Union regulation designed to ensure fair competition and greater consumer choice in digital markets. It targets large online platforms, known as 'gatekeepers,' such as major search engines, app stores, and social networks, by imposing rules that prevent them from abusing their dominant market positions. The DMA aims to create a more level playing field for smaller businesses and startups, foster innovation, and give users more control over their digital experiences. By setting clear obligations and prohibitions, the DMA seeks to curb unfair practices and promote a healthier, more competitive digital ecosystem across the EU.
