Son of Flubber
The first use of regularly scheduled closed captioning on American television occurred on March 16, 1980. Sears had developed and sold the Telecaption adapter, a decoding unit that could be connected to a standard television set. The first programs seen with captioning were a "Disney's Wonderful World" presentation of the film "Son of Flubber" on NBC, an "ABC Sunday Night Movie" airing of "Semi-Tough", and "Masterpiece Theatre" on PBS.
