The Invention of the Phonograph

The video explores Thomas Edison's groundbreaking work in sound recording, starting with his 1877 discovery of using a needle to etch sound onto a medium. It details the mechanics of the phonograph, which records sound by etching grooves into tinfoil wrapped around a brass cylinder. Edison's first recording was his voice reciting 'Mary Had a Little Lamb.' The video also covers Emile Berliner's development of the gramophone, which used a flat disk instead of a cylinder, marking the beginning of the recording industry.
