Columbia Graphophone Company
Columbia Graphophone Co. Ltd. was one of the earliest phonograph, gramophone companies in the United Kingdom. Founded in 1917 as an offshoot of the American Columbia Records, Columbia Phonograph Company, it became an independent British-owned company in 1922 in a management buy-out after the parent company went into receivership. In 1925 it acquired a controlling interest in its American parent company to take advantage of a new electrical recording process.

The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in.
