Wireless telephony has reached a remarkable stage of efficiency, but there is still the missing link – we cannot see the artistes or the announcer in the studio. The position of wireless to-day is analogous to the film industry a few years ago. We were then satisfied with silent films, but talkie picture technique is now so perfect that silent films have ceased to attract us. With the talkies we have speech and vision synchronised, and wireless cannot be considered as perfect until television and speech are similarly synchronised. Television to-day is on the brink of great developments. Many firms are experimenting with high definition television, and it would seem that mechanical television will not provide the solution. Television will probably be brought much nearer to perfection by means of the cathode-ray oscillograph. The problem will be solved by electrical rather than mechanical means.
