Closed captioning  displays the audio portion of a television program as text on the television screen.
It provides a critical link to news, entertainment and other televised information for individuals who are deaf or hard-of-hearing. For individuals whose native language is not English, English language captions improve comprehension and fluency.
Closed captions can be turned on or off via a television’s remote control devices or on-screen menu. The FCC does not regulate captioning of home videos, DVDs or video games.
