THE definitive textbook on captioning has been written by Gary Robson, a techie married to a court reporter who participated in its very creation.
“Inside Captioning,” is published by
CyberDawg Publishing .
Some highlights from Chapter 2, The History of Captioning.
The timeline begins in 1970 when the National Bureau of Standards began experimenting with
time coding and putting data in the VBI (vertical blanking interval) which eventually lead
to the idea of captioning.
The first captioning agency, WGBH,
began in 1971.
The BBC and PBS began captioning in 1972.
The FCC reserved Line 21 of the vertical blanking interval for transmitting closed
captions in 1976.
In 1982, the Academy Awards were captioned live!
Captioning experiments were conducted throughout the 80's, and in
1990, the Television Decoder Circuitry Act was signed into law and the
Americans with
Disabilities Act was passed.
In 1994, the Information Superhighway speech by Vice President Al
Gore became the first captioned event in cyberspace!
