Lead: If Peter Goldmark had had his way, television would have never been broadcast in black and white.

Intro.: A Moment in Time with Dan Roberts.

Content: By the late 1920s most of the technical problems of TV broadcasting were solved. A way had been found to convert light into electricity. The transmission of this electrical signal would be done just like radio, but the major obstacle proved to be the way in which the signal would picked up or scanned. Television is in many ways similar to a motion picture. Characters in a movie don’t move. Motion picture film is simply a series of still photographs put end to end and run so fast across the screen that the mind of the viewer gets the impression of movement. Television operates in basically the same way. Hundreds of frozen images per second are picked up or scanned by the camera, converted to electricity, and then sent on to the TV set which sits the next room or fifty miles away and reconverts the signal.
