A screen quota is a country's legislated policy that enforces a minimum number of days each year for the cinematic screening of that country's own films (and sometimes a minimum number of said films each year) in order to protect the status of those films, primarily as a method of preventing foreign markets from making inroads into the country's domestic film market. The screen quota system originated with the United Kingdom's 1927 Cinematograph Films Act, with other countries such as Brazil, France, Greece, Italy, Japan, Pakistan, South Korea, and Spain subsequently enforcing their own screen quotas.
