'Only RCA Victor has the "Impac" case -- so tough, it's guaranteed for five years in normal use.'
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

In radio communications, a radio receiver, also known as a receiver, wireless or simply radio is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation...

The RCA Corporation was a major American electronics company, which was founded as the Radio Corporation of America in 1919. It was initially a wholly owned subsidiary of General Electric (GE); however, in 1932, RCA became an independent company after GE was required to divest its ownership as part of the settlement of a government antitrust suit.
An innovative and progressive company, RCA was the dominant electronics and communications firm in the United States for over five decades. RCA was at the forefront of the mushrooming radio industry in the early 1920s, as a major manufacturer of radio receivers, and the exclusive manufacturer of the first superheterodyne models. RCA also created the first American radio network, the National Broadcasting Company (NBC). The company was also a pioneer in the introduction and development of television, both black-and-white and especially, color...
RCA's seemingly impregnable stature began to weaken in the mid-1970s, as it attempted to diversify and expand into a multifaceted conglomerate. The company suffered enormous financial losses in the mainframe computer industry and other failed projects such as the CED videodisc. In 1986, RCA was reacquired by General Electric, which over the next few years liquidated most of the corporation's assets. Today, RCA exists as a brand name only; the various RCA trademarks are currently owned by Sony Music Entertainment and Technicolor, which in turn license the brand name to several other companies including Voxx International, Curtis International, AVC Multimedia, TCL Corporation, and Express LUCK International, Ltd. for their various products...
RCA originated as a reorganization of the Marconi Wireless Telegraph Company of America (commonly called "American Marconi"). In 1897, the Wireless Telegraph and Signal Company, Limited, was founded in London to promote the radio (then known as "wireless telegraphy") inventions of Guglielmo Marconi. As part of worldwide expansion, in 1899 American Marconi was organized as a subsidiary company, holding the rights to use the Marconi patents in the United States and Cuba. In 1912 it took over the assets of the bankrupt United Wireless Telegraph Company, and from that point forward it had been the dominant radio communications company in the United States...
The Navy, claiming it was acting with the support of President Wilson, looked for an alternative that would result in an "all-American" company taking over the American Marconi assets... officers proposed that GE purchase American Marconi, and use the assets to form its own radio communications subsidiary... November 20, 1919, transformed American Marconi into the Radio Corporation of America...
GE's traditional electric company rival, the Westinghouse Electric & Manufacturing Corporation, had also purchased rights to some critical patents, including one for heterodyne receiving originally issued to Reginald Fessenden, plus regenerative circuit and superheterodyne receiver patents issued to Edwin Armstrong. Westinghouse used this position to negotiate a cross-licensing agreement, effective July 1, 1921, that included a concession that 40% of RCA's equipment purchases would be from Westinghouse. Following these transactions, GE owned 30.1% of RCA's stock, Westinghouse 20.6%, AT&T 10.3%, and United Fruit 4.1%, with the remaining 34.9% owned by individual shareholders...
