The widespread adoption of digital music formats, such as CD or satellite radio, has displaced phonograph records and resulted in phono inputs being omitted in most modern amplifiers. Some newer turntables include built-in preamplifiers to produce line-level outputs. Inexpensive and moderate performance discrete phono preamplifiers with RIAA equalization are available, while high-end audiophile units costing thousands of dollars continue to be available in very small numbers.

During its first century the phonograph has had wide-ranging effects on society. Were it not for the phonograph, the performances of great musicians and the voices of famous and interesting people would have been lost to history. Collections of musical discs in the home have broadened the appreciation of music and have changed people's musical tastes.

The earliest method of recording and reproducing sound was on phonograph cylinders. Commonly known simply as "records" in their era of greatest popularity (c. 1888–1915), these cylinder shaped objects had an audio recording engraved on the outside surface which could be reproduced when the cylinder was played on a mechanical phonograph. The competing disc-shaped gramophone record system triumphed in the market place to become the dominant commercial audio medium in the 1910s, and commercial mass production of phonograph cylinders ended in 1929.

Sounds that have been recorded on a disc can be re-created, or played back, by a phonograph. As the stylus attached to the phonograph's arm tracks the spiral groove of the rotating disc, the patterns cut into the groove cause the stylus to vibrate.

The "phonograph", or "gramophone", or "turntable" remained a common element of home audio systems well after the introduction of other media such as audio tape and even the early years of the compact disc. They were not uncommon in home audio systems into the early 1990s.
