ProPublica is known for long-form investigations on government, business, health care, criminal justice, education, and abuses of power, often built from months of reporting and document work. The catalogue also includes major data journalism projects, explanatory pieces tied to ongoing investigations, and partnerships with local and national news outlets that extend the reach of its reporting. Unlike ad-driven publishers, ProPublica operates as a nonprofit supported by donations and grants, so its journalism is free to read without a standard subscription paywall. Its audience includes readers who actively search for investigative journalism, watchdog reporting, and accountability news rather than quick headline summaries. A notable strength is its record of impact: stories frequently lead to official inquiries, policy debate, or follow-up reporting across the wider news industry. The trade-off is pace and scope, since ProPublica publishes fewer stories than general news outlets and concentrates on public-interest investigations instead of broad daily News & Media coverage.
