The Digital Services Act (DSA) is an EU regulation adopted in 2022 that addresses illegal content, transparent advertising and disinformation. It updates the Electronic Commerce Directive 2000 in EU law, and was proposed alongside the Digital Markets Act (DMA).
The DSA applies to online platforms and intermediaries such as social networks, marketplaces and app stores. Key requirements include disclosing to regulators how their algorithms work, providing users with explanations for content moderation decisions, and implementing stricter controls on targeted advertising. It also imposes specific rules on "very large" online platforms and search engines (those having more than 45 million monthly active users in the EU).
