The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods: * The Acoustic era (1877–1925) * The Electrical era (1925–1945) * The Magnetic era (1945–1975) * The Digital era (1975–present)
