 The production of multiple versions of export-bound talkies in different languages (known as "Foreign Language Version"), as well as the production of the cheaper "International Sound Version", a common approach at first, largely ceased by mid-1931, replaced by post-dubbing and subtitling.Despite trade restrictions imposed in most foreign markets, by 1937, American films commanded about 70 percent of screen time around the globe.Just as the leading Hollywood studios gained from sound in relation to their foreign competitors, they did the same at home.
