OGG is a wrapper/container format for Vorbis sound data and various other audiovisual bitstreams developed by the Xiph open source project. Although the initial specification and IANA registration called for the .ogg extension and application/ogg mimetype, whatever content was inside the wrapper, the September 2008 RFC 5334 changed that recommendation and registered audio/ogg and video/ogg mimetypes with corresponding .oga and .ogv extensions for content that is primarily audio or video respectively. The .ogx extension was introduced for use with content that incorporated the OGG Skeleton and for which application/ogg remained appropriate. The .ogg extension was grandfathered to refer to OGG audio with a Vorbis audio encoding. The .spx extension should be used for an OGG audio file with the Speex encoding.

Because OGG formats are free and open-source, not proprietary as many other formats are, they are preferred by many "free-media" projects including Wikipedia, but this causes some issues for people attempting to view/listen to them, since some devices (e.g., Apple's iOS devices) don't support the OGG formats, and others (e.g., Windows PCs) don't have "out-of-the-box" support until you install codecs, plug-ins, or software for it. Some of the proprietary formats have wider support in consumer devices in their default configurations.
