Erlangen, Germany (July 22, 2005)–The MP3 name celebrated its tenth anniversary on July 14. On that day in 1995, researchers at Fraunhofer Institute for Integrated Circuits IIS adopted .mp3 as the file name extension for their new audio coding technology, ISO standard IS 11172-3 “MPEG Audio Layer 3.”
The extension emerged as the unanimous winner of an internal poll at Fraunhofer IIS. In an email dated July 14, 1995, the new file extension was proclaimed:
Date: Fri, 14 Jul 1995 12:29:49 +0200
Subject: Layer3 file extension: .mp3
this is the overwhelming result of our poll: everyone voted for .mp3 as extension for ISO MPEG Audio Layer 3!
As a consequence, everyone please mind that for WWW pages, shareware, demos, and so on, the .bit extension is not to be used anymore.
There is a reason for that, believe me 🙂

The naming was the conclusion of years of research and development by a team of up to 40 engineers. The format’s international standardization in 1992 ensured worldwide compatibility–that fact and the public MP3 source code guarantee that billions of existing MP3 files can still be played by generations of audiophiles to come.
In 1992, MP3 was in fact so far ahead of its time that the industry considered the technology far too complex for practical application. It turned out, however, that its development was the bottom line advancement in audio coding. It is estimated that over 80 million MP3 players will be sold worldwide in 2006.
