...inaugurated the Columbia Phonograph Broadcasting System.
Sixteen stations were on board for the 3:00 P.M. opening show:
KMOX St. Louis
KOIL Council Bluffs
WOWO Fort Wayne
The Opening Day program featured a performance of "The King's Henchman" by a cast from the Metropolitan Opera. Other programs featured classical selections by members of the New York Philharmonic and the Philadelphia Symphony Orchestra, among others.
Weren't those the days? But record and phonograph sales were on the decline, so the young broadcasting company run by Arthur Judson struggled. From everything2: "However, with most major advertisers firmly committed to NBC, Judson and Columbia were losing money and sold the network to three men, Jerome Louchheim, Ike Levy, and Leon Levy. The three turned around and sold the network to William Paley, who happened to be Leon Levy's fiancee's brother. The Paley family had made its money as owners of the La Palina cigar company, and William Paley became interested in radio as a result of buying advertising time on various local radio stations."
