MP3 stands for MPEG-1 Audio Layer III, a method for strongly compressing audio data.
The technology is largely developed at the Fraunhofer Institute in Germany.

This makes it possible to share music easily over the internet.
An entire CD can suddenly fit into just a few megabytes of storage.
In the late 1990s, the first MP3 players and music software appear.
Music sharing through online platforms and file-sharing networks grows rapidly.
