This film is of the Columbia works in the UK. Columbia US went into receivership in 1922 and I recall Lewis Sterling, Managing Director of Columbia UK arranged for Columbia UK to acquire the ailing Columbia US to gain access to the Western Electric Process of electrical recording in early 1925. Sterling steered Columbia thru turbulent times until the HMV Columbia merger in the UK in 1931. Columbia Records drifted aimlessly through the depression until Wiliam Paley of CBS bought Columbia Records in 1938.
Sterling also was the genesis of CBS: (below courtesy of Eyes of a Generation

In early 1927 Arthur Judson, the impresario of the Philadelphia and New York Philharmonic orchestras, approached the National Broadcasting Company (NBC), which at the time was America’s only radio network, with an idea to promote classical music by airing orchestra performances. NBC declined. Undaunted, Judson founded his own broadcasting company, which he named United Independent Broadcasters, Inc. (UIB).
Lacking a strong capital base, UIB struggled to stay afloat. However, in the summer of 1927, Judson found a rich partner in the owner of Columbia Phonograph Company, Louis B. Sterling. Columbia Phonograph bought UIB's operating rights for $163,000. The new company was named the Columbia Phonograph Broadcasting System. Columbia Phonographic took over on September 18, 1927, with a presentation by the Howard Barlow Orchestra with network affiliate WOR in Newark, New Jersey, feeding fifteen other UIB network stations. Operational costs were steep, particularly the payments to AT&T for use of its land lines, and by the end of 1927, Columbia Phonograph wanted out. In early 1928, Judson sold the network to brothers Isaac and Leon Levy, owners of the network's Philadelphia affiliate WCAU, and their partner Jerome Louchenheim. Soon after, the Levy brothers had involved their relative, 26-year old William S. Paley, the son of a well-to-do Philadelphia cigar maker. With the record company out of the picture, Paley quickly streamlined the corporate name to Columbia Broadcasting System. Paley had come to believe in the power of radio advertising since his family's La Palina cigars had doubled their sales after young William convinced his elders to advertise on radio the year before.
Although the network was growing, it did not own a radio station of its own…yet. In December of 1928, CBS bought A.H. Grebe's Atlantic Broadcasting Company in New York City with the call letters WABC (no relation to the current WABC), which would become the network's flagship station.
In 1944, when NBC was forced to sell off one of it's networks, it sold NBC Blue which became the ABC Network. In 1945 in New York City, the flagship radio stations were NBC's WEAF 660kHz, ABC's WJZ 770kHz and CBS's WABC 880kHz. CBS obviously wanted to do a swap of call letters and so today (2023) WEAF is now sports station WFAN 660, ABC is WABC 770 and CBS is WCBS 880.
