DivX
From DigiWiki
The DivX codec is based on MPEG-4 video compression standard, designed primarily for video transfer over low to mid bandwidth networks (eg. Internet, WAP ...).
There are in fact 3 major versions of the codec, all name DivX.
The oldest version, a hacked version of Microsoft's MPEG-4 V3 implementation, is often referred to as the "DivX ;-) Codec". The hacked nature of the codec means it's legality has always been in question. The version number used is DivX 3.x.
Project Mayo was an open-source project started to replace DivX ;-) 3.x with a legal, developed from scratch version of the codec, OpenDivX.
The work done during Project Mayo allowed DivX for Windows/Linux/Mac/... to be produced. It is a commercial development, with free versions of the codec available for basic playback and encoding, and a paid for version with more advanced features. The version numbering started at 4.0 and is now in version 6.x.
