An oggcast is a podcast recorded and distributed exclusively in the Ogg vorbis audio codec and/or other similarly free codecs. For example, a podcast distributed both in the non-free mp3 format and the free Ogg Vorbis format would not technically meet the definition of an oggcast. In contrast, a podcast distributed in both the Ogg Vorbis and Speex codecs would meet the strict definition of an oggcast. The term oggcast is a combination of the word "ogg" from the term Ogg Vorbis, and the syllable "cast", from "broadcast". History The exact timeline of the term oggcast is uncertain, however, The Linux Link Tech Show, one of the longer running Linux podcasts still in production, has a program in the Ogg Vorbis format in its archives from January 7, 2004. Given that a stable release of Ogg Vorbis did not appear until July 19, 2002, it is very likely that the term oggcast was coined sometime between 2002 and 2004. Rationale Oggcasters tend to be broadcasters who prefer not to use audio and video codecs that have patent and/or licensing restrictions, such as the mp3 codec. * Ogg Vorbis may produce better audio quality with a smaller file size than alternative codecs such as aac or mp3. However, this has not been proven conclusively. * Ogg Vorbis is not bound by patents and is considered "free software" in the sense that no corporate entity owns the rights to the format. Some people feel that this is a safer container for their multimedia content for this reason. Disadvantages: * Oggcasters can generally not reach as wide of an audience as more traditional podcasters. This is mainly due to the lack of native Ogg Vorbis support in Microsoft's Internet Explorer and Apple's Safari web browser, and the lack of Ogg Vorbis support in many mobile audio devices. Oggcasts Oggcast planet maintains a central list of oggcasts. Some notable (but not all inclusive) oggcasts are as follows: * Cerebral knights * Crivins * GNU World Order (hosted by ) * Information underground * Juiced Penguin * Kernel Panic Oggcast * LibreCAST * Libre.fm * Lotta linux links * MythTV cast * * TuxJam
