Why were you shown that ad? Most platforms still won
Article 39 of the EU Digital Services Act (DSA) requires very large online platforms (VLOPs) and very large online search engines (VLOSEs), including social media platforms like Instagram, shopping platforms like Temu and app stores like Google Play, to provide a database of all advertising shown and transparency as to who paid for each ad, which user demographics were targeted and how many users were reached in each country.
