MP3
In the 1980s, Dieter Seitzer started the development of a code for audio format of high-quality. Together with his team at the German Fraunhofer Institut in Erlangen, the professor had the idea to create code with a low bit-rate. The German institute received the patent for MP3 in 1989. MP3 was then passed to the International Organisation for Standardisation. In the same year the MP3 was included into MPEG-1 specification. (MPEG means Moving Picture Experts Group).
