December: National Closed‐Captioned Television Month

With the start of a new decade in 1980, the public witnessed the arrival of a significant new technology, closed‐captioned television. The culmination of nearly a decade of research and development, closed‐captioned television opened up a new world for the hearing‐impaired. Closed captioning provides a line of on‐screen, written messages co‐ordinated with the sound of the television program. These captions are “closed” in that they are visible only to viewers who have specially designed adapters, known as decoders, to make the words appear on the screen. More than just subtitles, captioning transcribes narration and sound effects as well as dialog. At last, over sixteen million hearing‐impaired individuals in the United States can read what they cannot hear on television.
