Thomas Edison invented the phonograph while working on improving the telegraph. The phonograph allowed sound and music to be recorded and listened to at later times. This led to the spread of people who could not attend live musical performances, to be able to listen to music.
Invention of Disc Gramophone
In 1887 Emile Berliner invented a gramophone player that used discs instead of cylinders. The discs did not break as easily and were easier to mass produce. This would lead to an increase in music production and easier acess for people to listen to music.
Production of First Cassette Tape
RCA produced the first cassette tape in 1958 even though this format never gained popularity. This invention made the listening of music easier by being smaller and easier to carry around. Phillips produced the first Compact Cassette in 1964.
