Region codes were officially implemented to restrict the sale of titles to designated regions, so that, for example, a DVD could be released in the United States before the movie was released to the cinemas in Europe. However, region code enforcement has been discussed as a possible violation of World Trade Organization free trade agreements or competition law. This, supposedly, means that all DVD players sold in their territories have to be region-free.
