the companies agree to certain minimum fees, residuals, and other benefits for WGA writers they contract. It is negotiated by a committee of the WGA. Screen Writers Guild credit system The early industry had taken efforts to prevent writers from unionizing. Although the SWG was formed in 1933, it encountered resistance until May 1941, when it signed a deal with the studios that gave the Guild, among other rights, the final say on writing credits.

Any participant writer, even deceased, has the right to be involved in the credit determination process (this may be through a representative, such as an agent). Up to three writers, or two teams of
