Use of video-tapes in psychological medicine.

It was in 1947 that perhaps the first use was made of closed-circuit television when the proceedings of five surgical operations were transmitted to a group of physicians at a medical meeting at Johns Hopkins (Berger, 1970). In psychiatry, the first reports of the use of closed circuit television in the teaching of medical students and psychiatric nurses, as well as residents were probably by Wittson and Dutton (1956) and later, Tucker (1957) and his colleagues reported on its use in treatment of the mentally ill.
