July 14, 1995: The MP3 file format receives its official name as the new .bit file extension gets changed to .mp3. The technology allows compression of a standard CD .wav file to one-tenth its original size, courtesy of some smart algorithms.
The format will revolutionize the music industry — and put Apple on the road to world-conquering dominance.
A thousand songs in your pocket
The MP3 enables easy sharing of music tracks online and makes music more portable than ever. Apple’s iPod will become the world’s best-known MP3 player, quickly capitalizing on the new format.
The MP3 gave people the ability to, as Apple would later phrase it, “put a thousand songs in your pocket.” MP3 was a significant advance — and it all came down to the file size.
While it might not sound like much in today’s world of broadband connectivity, reducing song file sizes from 32MB to 3MB proved massive in the mid-1990s.
At the time, the bitrate of a typical modem was just 28.8k or 56k. That meant that a 32MB file would take literally hours to download. With significantly smaller hard disks than today, it also meant you’d struggle to hold much more than an album or two on a typical computer. (For example, the Power Mac 7100, which many Apple owners would be using in 1995, came with a hard drive ranging from 250MB to 700MB in size.)
How MP3 made file sizes smaller
The genius of MP3 was finding a way to encode data using inexact approximations and partial data discarding to reduce the file size of an audio track, without sounding noticeably worse than uncompressed audio.
The first MP3 encoder was called I3enc, created by the Fraunhofer Institute for Integrated Circuits. (The institute held onto ownership of the MP3 format until this year.)
It didn’t take long before portable MP3 players started popping up. However, it wasn’t until October 2001, after Steve Jobs returned to Apple and took over as CEO, that the iPod arrived on the scene. With more capacity for holding MP3s than rival products, and the ease of iTunes, the device put Apple on the path to its current status as a technological powerhouse.
And none of it would have happened without the MP3.
