A common 21st century phrase is ‘podcast’ an odd combination of the words iPod and Broadcast; the iPod being, Apples market dominatingly popular portable MP3 player. This expression is used to define a technology that lets users routinely download available audio files for listening to later, and is no longer exclusive to the iPod as many other software and hardware combinations now be used for the very same thing.
The roots of podcasting most likely lie in the blogging world as it is the natural progression to broadcasting information via the written word. I’m sorry for chucking another buzzword in the form of ‘blogging’, but with technology suddenly becoming cool there are dozens of new ones making their way in to our vocabularies. A blog, for those of you that don’t know, is an online journal that is frequently updated and intended for the general public. I should also just mention a technology known as RSS (Really Simple Syndication) which provides a continuous feed detailing updates that have been made to a particular data source; a podcast site for example.
