"Today, the gray monochrome of the receiver screen has given way to vivid color. The camera is equipped with a sophisticated zoom lens instead of the cumbersome turret, and the ponderous boom microphone has been replaced by a tiny cylinder about the neck.

This handbook updates Extension television in the light of these developments."--Page 1
