Closed Caption Television: Today and Tomorrow

This article, written in 1980 by Barry Jay Cronin, Ph.D., was prepared for the Symposium on Research and Utilization of Educational Media for Teaching the Deaf. For many years an annual media symposium was held at the University of Nebraska, Lincoln. This paper provides a general background on the history of closed captioning and how it has evolved to that point. As Dr. Cronin states, "No technology can remain static and be successful for long." Also explains what Line 21 is, and describes the closed-captioning process.
