An aggregator site is a digital platform whose primary function is to pull together content—usually news articles, blog posts, or social media items—from multiple third-party sources and present them in a single, navigable interface. Aggregators range from algorithmic feeds such as Google News and Apple News to human-curated portals like Drudge Report or Real Clear Politics, and to community-voted boards such as Reddit or Hacker News. Some, like Memeorandum, focus on clustering stories by topic to show which outlets are covering what.
Aggregators play a significant role in shaping political discourse because they influence which stories gain visibility. By selecting, ranking, or excerpting headlines, they exercise editorial power without necessarily producing journalism. For researchers and Model UN delegates, aggregators are useful for rapidly scanning cross-source coverage of an issue—seeing, for instance, how a UN Security Council vote is framed by Reuters, Al Jazeera, Xinhua, and the BBC simultaneously.
Their rise has generated ongoing legal and economic disputes with original publishers. Key tensions include:
- Copyright and "snippet" use: The EU's 2019 Directive on Copyright in the Digital Single Market (Article 15) created a neighbouring right for press publishers, requiring platforms to license news snippets. Similar laws followed in Australia (News Media Bargaining Code, 2021) and Canada (Online News Act, 2023).
- Revenue diversion: Publishers argue aggregators capture advertising value generated by others' reporting.
- Filter bubbles: Algorithmic aggregation can narrow exposure to diverse viewpoints, a concern raised in research on platform governance.
Aggregators are distinct from content farms (which produce low-quality original material) and from syndication services like the Associated Press (which license full articles to subscribing outlets). They are also distinct from social media platforms, though the line has blurred as Facebook, X, and TikTok increasingly function as de facto news aggregators for younger audiences, according to repeated Reuters Institute Digital News Reports.
Example
In 2021, Australia's News Media Bargaining Code forced Google and Facebook to negotiate payments with publishers such as News Corp for news content surfaced through their aggregation services, briefly prompting Facebook to block Australian news links.

A search engine indexes the entire web and returns results in response to user queries, while an aggregator curates or algorithmically assembles a continuously updated feed focused on news or a specific content type.
