Minor nitpick: the Fraunhofer Society is an organization with multiple Institutes across Germany (plus some Centers outside Germany), each working on different areas of applied science. MP3 was developed at the Fraunhofer Institute for Telecommunications.
Since we are nitpicking...mp3 was invented by the Fraunhofer Institute for Integrated Circuits, the Fraunhofer Institute for Telecommunications is a relatively new addition to the Fraunhofer Society, before 2003 it was called Heinirch Herz Institute. If I recall correctly, HHI was instrumental in developing the H.256 Video Coding Standard
