In 1919, restaurateur Louis Sherry announced an "alliance" with the Waldorf-Astoria that involved both his candies and catering services. Although it was not disclosed at that time, at some point, ownership of Louis Sherry Inc. was significantly vested in "Boomer-duPont interests", a reference to Lucius M. Boomer, then chairman of the Waldorf-Astoria, and T. Coleman du Pont. Upon his death that year, William Waldorf Astor was reputed to have been worth £200 million, which he left in trust for his two sons Waldorf and John Jacob. His half share of the Waldorf Astoria and the Astor Hotel at the time were reported to have been worth £10 million. On the evening of November 15, 1926, the National Broadcasting Company broadcast its inaugural program from the grand ballroom of the old Waldorf-Astoria. Among the entertainers heard by radio listeners was Will Rogers. The network became the Red Network on January 1, 1927, when NBC launched its second network, designated the Blue Network. An antitrust suit forced the sale of the Blue Network in 1942; it became the American Broadcasting Company.
