Sometimes, people make movies that they want others to see. But they can't just hand out DVDs to everyone in the world. That would take too long and be too expensive. So they work with companies called distributors.
These distributors help the creators of the movie get the movie out to different places like movie theaters, streaming services, or on DVDs. They make deals with these places to put the movie out there.
Once the deal is made, the distributor sends copies of the movie to each of those places. Then, people can pay to watch the movie in the theater or rent it on DVD or stream it on the internet.
Overall, the distributor helps the movie get out to people and makes sure everyone is paid.
