RCA Broadcast News, October 1946
RCA introduces television’s first workhorse…the TK30 Image Orthicon Camera…in a multi-page article. This was the first IO camera, the first camera with a rotatable lens turret, and the first to be mass produced. Many of these cameras were in use all the way up to the time that color finally took over in 1965. On page 20, there is another multipage article on the new RCA Microwave equipment, which was greatly improved and needed to make the TK30 images even better from the field.
