The Bell Telephone Hour is a concert series which began April 29, 1940, on NBC Radio and was heard on NBC until June 30, 1958. Sponsored by Bell Telephone as the name implies, it showcased the best in classical and Broadway music, reaching eight to nine million listeners each week. It continued on television from 1959 to 1968. Throughout the program's run on both radio and television, the studio orchestra on the program was conducted by Donald Voorhees.
The TV show, seen on NBC from January 12, 1959, to the summer of 1968, was one of the first TV series to be telecast exclusively in color, using the color TV system perfected by RCA in 1954. It aired every week on Friday evenings at 10:00 PM, then was switched to Tuesday evenings at 10:00 P.M. in 1963. It was noted for its Christmas specials, frequently featuring opera stars as well as stars of musical theater and ballet. In the fall of 1965, the show was switched to an earlier time slot of Sundays at 6:30pm. Beginning in 1965, the program sometimes had to share its time slot with an NBC news series called Actuality Specials on NBC, and was telecast every other week. In the fall of 1963, the program alternated with The Andy Williams Show. During its last season, 1967-1968, the program was switched back to its old Friday night time slot and the format changed from a videotaped and mostly musical presentation to filmed documentaries about classical musicians made on location. By this point, The Bell Telephone Hour was seen as a relic of a bygone era in television history. One of the most notable of the Bell Telephone Hour documentary programs combined a tour of the Museo del Prado in Madrid, with performances by such noted Spanish musicians as Andrés Segovia, Alicia de Larrocha, and Victoria de los Ángeles. Another was a profile of Cleveland OrchestraconductorGeorge Szell. This one was not a biography of Szell, but a documentary showing how he worked with the orchestra. One of the last, and most notable episodes done in the videotape format, was "First Ladies of Opera", featuring Joan Sutherland, Leontyne Price, Renata Tebaldi and Birgit Nilsson, all on one program. In 1976, footage from the TV series was edited into a 90-minute retrospective TV special entitled The Bell Telephone Jubilee, aka Jubilee, hosted by Bing Crosby and Liza Minnelli. NBC Staff announcer Mel Brandt was the series announcer. ABC staff announcer Scott Vincent hosted the 1962 season finale, "Till Autumn."
In 1947, a 27-minute black-and-white short subject entitled Rehearsal: The Telephone Hour, was released to theaters. Originating in NBC's Studio 6B at 30 Rockefeller Plaza, the film featured, in addition to Voorhees and the orchestra, operatic bass Ezio Pinza and opera mezzo-soprano Blanche Thebom singing arias. It simulated a rehearsal of the popular program, complete with a commercial announcement, and then, near the end, segued to what was presumably the actual radio broadcast.
