MP3 Patented in US

There is no official logo for MPEG Audio Layer III, otherwise known as MP3

November 26, 1996

United States Patent 5,579,430 is granted to the Fraunhofer Institut in Germany for a “digital encoding process”, the technology used in MEPG Audio Layer III, more commonly known as MP3. MP3 technology paved the way for the digital music industry by creating a high-quality format that was compressible so that many songs could fit on the relatively small data storage devices of the time. Fraunhofer had started work on compressing music as far back as 1977, began work on what would become MP3 in 1987, and was awarded a patent in Germany in 1989.
