How Free Legal Streaming Works in the US

Most free platforms operate under the AVOD model (Advertising Video On Demand). Short ads fund content licensing, allowing viewers to watch legally without subscriptions or payments.

Public services like Kanopy are funded by libraries and educational institutions, not advertising.

Sites to Avoid

Websites such as 123Movies, FMovies, Putlocker, and similar clones are not licensed in the US. They often carry malware risks and violate copyright law. They are not recommended.
