1926 Bulova produces the nation's first ever radio spot commercial, "At the tone, its 8 PM, B-U-L-O-V-A Bulova watch time."
1941 Continuing its tradition of advertising firsts, Bulova airs the first television commercial: a simple picture of a clock and a map of the United States, with a voice-over proclaiming, "America runs on Bulova time." 1941 also marks the year that the Bulova Board of Directors adopts a resolution to manufacture products for national defense at actual cost. Throughout World War II, having perfected the skill of creating precision timepieces, Arde Bulova, Joseph's son, works with the U.S. government to produce military watches, specialized timepieces, aircraft instruments, critical torpedo mechanisms and fuses.
