OT: Why is captured DV footage '.AVI' ?

Hi, I was wondering, it says on the net that around 10 companies worked together to create the DV Codec...

"Companies involved were Matsushita Electric Industrial Corp (Panasonic), Sony Corp, Victor Corporation of Japan (JVC), Philips Electronics, N.V., Sanyo Electric Co. Ltd, Hitachi, Ltd., Sharp Corporation, Thomson Multimedia, Mitsubishi Electric Corporation, and Toshiba Corporation"

But a captured DV footage with 'DV' Codec becomes "AVI"
why is the 'AVI' extension used for the DV Codec? I don't see Microsoft on the '10 company list'

I believe that AVI is the wrapper for windows applications just like MOV is the rapper for mac (FCP,etc.). Guys, correct me if I'm wrong.

DV is a method of video compression. Beerandchips is correct, AVI is just the container, it can "contain" all types of video, either uncompressed or compressed with a variety of codecs. AVI is the standard container for Windows and MOV is the standard for Macs. Although, AVI can be used on Macs and MOV can be used on Windows.

DV is just raw data that is capture to the avi container. Avi is nothing more than a container for audio and video. Avi acts as wrapper and programs that can access avi open to the container to access the audio and video thats inside.

edit: John, you beat me to the answer. :)

And,......AVI, or Audio/Video Interleaved, will likely be soon replaced by WMV if microsoft keeps heading where they are heading. Again, it's just a box/wrapper/package that can contain any number of codecs. Or no codec.

And WMV can be considered as a container/wrapper also ?

What about uncompressed formats ?
