Well it's more like Activision is the publisher that owns the rights. So if CoD was a book, Activision owns the idea and Treyarch writes the book with some creative freedom, but does not own the ideas in the book. Activision then takes care of all of the expenses and other financial/legal and other things. Treyarch makes DLC, Activision approves. Treyarch makes patches and Activision approves them. The money goes to Activision and Activision redistributes it to all the contributors.Ya, that's what I meant to say lol. Activision just makes most of the profit while Treyarch develops the game.
