PopisDuMont Telecruiser - Early TV production truck.jpg
English: One of the first remote TV production trucks, the DuMont Telecruiser, built by DuMont Television Network in 1949. It is shown in this 1953 advertising illustration during broadcast, with side cut away to reveal the interior construction. The roof platform, accessible from inside through a hatch, allowed the large cameras to see over crowds (handheld cameras did not exist yet). The video feed was transmitted back to the studio through the microwave dish on the roof (communication satellites did not exist).
Alterations to image: cloned in some ground in front of the vehicle which was removed in the advertisement. The crosshatched lines in background are aliasing artifacts from scanning of halftone image.
This image is from an advertisement by Grant Pulley and Hardware Co., New York, without a copyright notice published in a 1953 magazine. In the United States, advertisements published in collective works (magazines and newspapers) are not covered by the copyright notice for the entire collective work. (See U.S. Copyright Office Circular 3, "Copyright Notice", page 3, "Contributions to Collective Works".) Since the advertisement was published before 1978 without a copyright notice, it falls into the public domain.
