The Adventures of Ozzie and HarrietEpisode: The Antique Vase (8/12/1945)

The Adventures of Ozzie and Harriet launched on CBS on October 8, 1944, moving to NBC in October 1948, and making a late-season switch back to CBS in April 1949. The final years of the radio series were on ABC (the former NBC Blue Network) from October 14, 1949 to June 18, 1954. In total 402 radio episodes were produced. In an arrangement that amplified the growing pains of American broadcasting, as radio "grew up" into television, the Nelsons' deal with ABC gave the network the option to move their program to television. -wikipedia.com
