Description:
This trade paper began in 1931 with a focus on radio, but as the TV industry expanded in the post-World War II era, the paper increasingly became devoted to television (even the title changed to BROADCASTING TELECASTING). Developments in technology, policy, advertising, and programming were covered. The paper's advertisements and articles reveal the intricate relationship among sponsors, stations, program suppliers, and station representatives -- the industry's term for middle-men who represented numerous local stations in negotiations with national sponsors. The success of particular stations or programming choices are frequently trumpeted in BROADCASTING'S advertisements -- always with the goal of selling more of something, such as a film program or a station's spot advertising time. -- Eric Hoyt, 2014

and'sound programs for many of the nation's leading TV stations A PERFECT FILM PROGRAM every time . . . high-definition, super-steady pictures . . . continuous, on-theair dependability— with this new sound-film projector that's designed specifically to meet the exacting needs of television stations. The film-drive mechanism and other mechanical features are precision-built in the RCA Brenkert plant . . . home of the famous projectors used by leading theatres around the world. The sound-head is the well-known RCA high-quality unit used in these projectors— modified to include a special, salient -pole synchronous motor. Here is the film projector that produces higher light output with negligible heating of the film gate or the film . . . enables you to project single frames as stills. Here is a film projector with great mechanical simplification—and with fewer moving parts for quieter, easier operation. It's easy to operate. It's simple to maintain . . . even oils itself! Auxiliary equipment for the projector includes a control rack with its pulsed light power supply, remote panels, and 10-inch picture monitor. A film camera multiplexer is available as accessory equipment (see diagram for operation). • • • To get the most from your newsreels, shorts, and feature films, overlook none of the advantages of this new 35-mm projector.

This ingenious RCA device eliminates the need for an additional film camera. It consists of a Vshaped mirror for reflecting images from either projector to film camera and a slide film projector for inserting station breaks, commercials, and special effects. How It works — Line A shows the pulldown timing of a standard 35-mm film projector (no lighting during 90° pulldown). Line B shows pull-down timing of the RCA 35-mm television projector — and the duration and repetition rate of the short intervals during which light passes through the film. Line C shows the projector lighting interval of the RCA 35-mm television projector. The "light-on" intervals are produced by a pulse-controlled camera lamp that produces an 800-microsecond flash every l/60th second. The picture images are projected onto the film camera pick-up tube during the retrace (blanking) interval of its scanning beam. The "storage" property of the tube permits scanning during the unlighted interval between flashes. Scanning releases the picture chargeconverts it into a video signal. A synchronizing generator keeps the projector and film camera in phase. 360° (1/24 SECOND) ■ 288» (1/30 SECOND) H UNLIGHTED INTERVAL (FILM CAMERASCAN) H1/60 SECOND ^ 5% IIGHTING INTERVAL TELEVISION,, FIELD TELEVISION FIELD TELEVISION FIELD TELEVISION FIELD TELEVISION FIELD TELEVISION FIELD * H TELEVISION FRAME »i reLBVtStOM BROADCAST EQUtRMEMT RAD to CORPORATtOM of AMERiCA EMGiMeERIMO PROOUCTS DKRARTMKMT, CAMDEM,M,J, In Canada; RCA VICTOR Company LImlfed, Montreal BROADCASTING • Telecasting January 10, 1949 • Page 9
