In the late 1960s, a man started experimenting. Malcom Norwood thought that deaf
people could enjoy television programs, too. He wanted to develop captions for
the programs. Norwood worked for the federal government’s Media Services and Captioned Films Division at the Bureau of Education of the Handicapped.
Norwood surveyed many hearing Americans. He wanted to see how they felt about seeing captions on the television screen. Too many people were against the idea. Norwood realized he had to develop another way of captioning - one that would not
bother hearing people.
In October of 1971, Norwood’s office signed a contract with WGBH-TV, a public television station in Boston. WGBH was hired to experiment with captions. They agreed to make a captioned television program for Norwood. That program was made. It was shown on television and at a special convention.
The type of captions made by WGBH could be seen on any television. No special equipment was needed. These were called “open captions”.
