Patents for a wax disc/cylinder gramophone are
granted to Chichester Bell, Charles Sumner Tainter and Alexander Graham Bell. Their improvement on
Edisons original phonograph is called a graphophone. What is lacks in sound volume compared
with Edisons tin-foil cylinders, it more than gains in clarity and reduced surface noise.
Although more suitable for listening through ear-tubes, it also allows for greater recording time
per cylinder by using a narrower groove pitch. It can be powered by foot-treddles or an electric
motor, resulting in a more consistent pitch.
Up to 60 per cent of major British newspapers, such as The Times, is devoted
to advertising.
