Very Large Online Platform

A Very Large Online Platform is a legal category created by the European Union for online services used by more than 45 million people per month within Europe. Think of it like a school: once the student body grows past a certain size, extra safety rules and dedicated staff kick in. When a service has that many users, the potential harm from misinformation or dangerous content spreading also grows, so the EU places heavier responsibilities on these services.

Once a service gets this label, it can no longer run ads targeted at minors, and it's banned from using sensitive personal data — like someone's sexual orientation, religion, or political views — to serve personalized ads. It also has to be more transparent about the criteria its recommendation algorithms use to select and display content. Services centered on search functions get a related but separate classification called a 'Very Large Online Search Engine,' and both categories come from the same EU law, the Digital Services Act.

What matters here is that this designation isn't applied based on what kind of service it is. Whether it's a conversational AI, a community forum, or a gaming platform, crossing that single user-count threshold puts it under the same regulatory framework.

Articles use it like this: "The European Commission designated Reddit and Roblox as Very Large Online Platforms (VLOPs), and ChatGPT as a Very Large Online Search Engine (VLOSE)." One easy point of confusion: VLOP and VLOSE sound similar but are separate categories. They're split by whether the service is a platform or a search engine, but both fall under the same law — the Digital Services Act — and face similarly strict obligations.
