in 1877 and patented in 1878. The invention soon spread across the globe and over the next two decades the commercial recording, distribution and sale of sound recordings became a growing new international industry, with the most popular titles selling millions of units by the early 1900s. The development of mass-production techniques enabled cylinder recordings to become a major new consumer item in industrial countries and the cylinder was the main consumer format from the late 1880s until around 1910.


Disc phonograph

The next major technical development was the invention of the

overtook the cylinder ca. 1910, and by the end of World War I the disc had become the dominant commercial recording format. In various permutations, the audio disc format became the primary medium for consumer sound recordings until the end of the 20th century, and the double-sided 78 rpm shellac disc was the standard consumer music format from the early 1910s to the late 1950s.

in 1949. In the US and most developed countries, the two new vinyl formats completely replaced 78 rpm shellac discs by the end of the 1950s, but in some corners of the world the ''78'' lingered on far into the 1960s. Vinyl was much more expensive than shellac, one of several factors that made its use for 78 rpm records very unusual, but with a long-playing disc the added cost was acceptable and the compact ''45'' format required very little material. Vinyl offered improved performance, both in stamping and in playback. If played with a good diamond stylus mounted in a lightweight pickup on a well-adjusted tonearm, it was long-lasting. If protected from dust, scuffs and scratches there was very little noise. Vinyl records were, over-optimistically, advertised as ''unbreakable''. They were not, but they were much less fragile than shellac, which had itself once been touted as ''unbreakable'' compared to wax cylinders.


Electrical recording

Between the invention of the phonograph in 1877 and the advent of digital media, arguably the most important milestone in the history of sound recording was the introduction of what was then called ''electrical recording'', in which a
microphone A microphone, colloquially called a mic (), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and publi ...
was used to convert the sound into an electrical signal that was amplified and used to actuate the recording stylus. This innovation eliminated the ''horn sound'' resonances characteristic of the acoustical process, produced clearer and more full-bodied recordings by greatly extending the useful range of audio frequencies, and allowed previously unrecordable distant and feeble sounds to be captured. Sound recording began as a purely mechanical process. Except for a few crude telephone-based recording devices with no means of amplification, such as the Telegraphone, it remained so until the 1920s, when several recent radio-related developments in

converged to revolutionize the recording process. These included improved microphones and auxiliary devices such as electronic filters, all dependent on electronic amplification to be of practical use in recording. In 1906,

four-track magnetic sound system. EMI (UK) was the first company to release commercial stereophonic tapes. They issued their first ''Stereosonic'' tape in 1954. Others quickly followed, under the His Master's Voice and Columbia labels. 161 Stereosonic tapes were released, mostly classical music or lyric recordings. RCA imported these tapes into the US. Two-track stereophonic tapes were more successful in America during the second half of the 1950s. They were duplicated at real time (1:1) or at twice the normal speed (2:1) when later 4-track tapes were often duplicated at up to 16 times the normal speed, providing a lower sound quality in many cases. Early American 2-track stereophonic tapes were very expensive. A typical example is the price list of the Sonotape/Westminster reels: $6.95, $11.95 and $17.95 for the 7000, 9000 and 8000 series respectively. Some RCA tapes released in the USA also cost up to $15. Record companies mixed most popular music singles into monophonic sound until the mid-1960s—then commonly released major recordings in both mono and stereo until the early 1970s. Many Sixties pop albums now available only in stereo were originally released only in mono, and record companies produced the stereo versions of these albums by simply separating the two tracks of the master tape. Magnetic tape transformed the recording industry. By the early 1950s, most commercial recordings were mastered on tape instead of recorded directly to disc. Tape facilitated a degree of manipulation in the recording process that was impractical with mixes and multiple generations of directly recorded discs. An early example is
