Closed captions were first publicly demonstrated on the PBS show 'The French Chef' in 1972, revolutionizing media accessibility and leading to federal mandates; today, they reach over 36 million Americans with hearing loss, and studies show they also improve learning outcomes for second-language learners by up to 20%.
