Over the years General Electric continued to innovate in a huge range of fields, and opened divisions specializing in everything from plastics to airplanes to electric fans. At the beginning of the 20th century, the company had the first voice radio broadcast in the world, the first electric toaster, and began work on vacuum tubes that would herald the dawn of the electronic age. In the 1910s and 1920s General Electric continued to innovate, setting a new altitude record with an airplane, making the refrigerator a common household word, and building the world’s largest electrical facility on the Panama Canal.
