ABSTRACT
What was the first demonstration in this country of combined sight and sound via the phone was staged in London recently. This was in connection with the booking of seats for a new film at Selfridges. The intending purchaser of seats went into a telephone booth which was in semi-darkness, took a seat before a television receiver and immediately he picked up the telephone receiver there appeared on the screen of the cathode-ray tube a picture of the booking clerk, who proceeded to discuss his requirements. After the business was completed the telephone receiver was replaced and this had the effect of cutting the transmission off.
