- Columbia_Grafonola abstract "The Columbia Grafonola is an early 20th century American phonograph. Grafonola derives its name from an internal horn disc Graphophone, which was introduced in 1907 and was mass produced by Columbia Graphophone Company.Prior to 1907, majority of Columbia phonographs depended almost exclusively on an external horn to shape and direct the sound. By 1912, internal horn machines such as Grafonolas became widely available and were outselling the external horn models.In 1915, Columbia Phonograph Company begun to introduce electrified models as majority of urban areas had been wired to electrical grids. The electrified Grafonola supported both alternating and direct currents from 110 to 220 volts. Electrified Grafonolas never gained the amount of popularity enjoyed by its acoustic models due to steep prices reaching as high as $250.00 and lack of electricity access in rural areas.".
