As you may be aware, widespread acceptance Captioning and Audio description came about as a result of grassroots effort in the Deaf and Hard of Hearing community. That effort resulted in the establishing a federal law requiring captioning.
By 1996, all new programming, with few exceptions, MUST be captioned. By 1998, 75% of older reruns MUST be captioned. The schedule for Spanish language shows is a few years back.
