Although the word "gramophone" referring to a player of disc records became a generic term, it was originally the trade name of the Gramophone Company and the records were therefore Gramophone Records. The "recording angel" trade mark used by the company in it's Berliner period was retained from 1902 to 1909, when Nipper and the gramophone appear and the label name changed in 1910 to "His Master's Voice". This was as a result of the company trying to copyright the word "Gramophone", unseccessfully. Gramophone records were available in three sizes: 7" (Gramophone), 10" (Gramophone Concert) and 12" (Gramophone Monarch) and were all single-sided.
