Why Portuguese subtitles matter
Portuguese is the sixth most spoken language globally, with 250 million speakers across Brazil, Portugal, Angola, Mozambique, and Cape Verde. Brazil alone has 215 million people and is the largest economy in Latin America. Portuguese subtitles are essential for reaching Brazilian audiences — Brazil has the highest social media engagement rates in the world and spends more time watching online video than any other country.
