Media Cloud
Open-source media analysis platform. Search and analyze news coverage across 60,000+ sources and 1 billion+ stories worldwide.
What should journalists know about Media Cloud?
Media Cloud is the most powerful open-source tool for understanding how news travels. Originally developed at Harvard's Berkman Klein Center and MIT's Center for Civic Media, it's now run as a consortium by the Media Ecosystems Analysis Group, University of Massachusetts Amherst, and Northeastern University. The platform indexes over 1 billion stories from 60,000+ news sources worldwide — the largest open-source news database that exists. Media Cloud Search lets you analyze how digital news covers specific topics: which outlets publish what, when coverage spikes, and how framing differs across media ecosystems. The Media Cloud Directory catalogs all 60,000+ sources with metadata. For journalists, the use cases are concrete: track how a story spread from a single outlet to national coverage, compare how left- and right-leaning media covered the same event, identify which outlets drove a narrative, or find underreported angles by seeing what everyone else missed. The platform moved from Harvard/MIT to its current consortium structure, which brought growing pains — some tools and documentation lag behind the ambition. The learning curve is real. But nothing else offers this scale of media analysis for free and open source. GDPR Note: Media Cloud indexes published articles, not private data.
Analyzing news coverage patterns at scale. Tracking how stories spread across media ecosystems. Comparing coverage framing across outlets and political leanings. Identifying which outlets broke a story and how it propagated. Academic and investigative media research.
Real-time news monitoring (there's a processing delay). Social media analysis (this covers news outlets, not Twitter or Facebook). Simple news searches — Google News is faster for quick lookups. Journalists who need a turnkey tool with no learning curve. Broadcast media analysis (primarily text-based digital news).

Privacy policy summary
Media Cloud collects account information for registered users. The indexed data consists entirely of publicly published news articles and metadata — no private or personal data is scraped. Terms of Use and Privacy Policy available on site. As an academic research tool, data practices are governed by university institutional policies. No advertising or commercial data monetization.
How to protect yourself:
Create an account with a professional email — some search features require login. Export and save your research results locally; as a nonprofit academic project, service continuity depends on ongoing institutional support and funding. Cross-reference Media Cloud findings with direct source verification — the platform indexes article metadata and content but automated processing can introduce classification errors. Understand that coverage of non-English sources is less comprehensive than English-language media. The 60,000+ source count includes varying levels of reliability — use Media Cloud's source metadata to filter appropriately.
Academic nonprofit with no commercial data incentives. Indexes only publicly published news content — no private data collection beyond user accounts. Open-source codebase allows independent security review. US-hosted at university infrastructure. The main risk is institutional: as an academic project, long-term service continuity depends on funding and institutional commitment. The transition from Harvard/MIT to the current consortium was bumpy. Adequate for media research purposes.
