From Wikipedia: A podcast, or generically netcast, is an episodic series of digital audio or video files which a user can download and listen to. It is often available for subscription, so that new episodes are automatically downloaded via web syndication to the user’s own local computer, mobile application, or portable media player. It is distinct from Internet radio, which involves streaming rather than downloading.
The word was originally suggested by Ben Hammersley as a portmanteau of “iPod” (a brand of media player) and “broadcast”. The files distributed are in audio format, but may sometimes include other file formats such as PDF or EPUB. Videos which are shared following a podcast model are called video podcasts or vodcasts.
Shizdiggity is a podcast created by Al Del Degan and Rea Hailley to share life lessons that they have learned about how to be happy, believe in yourself and just generally become the best that you can be.
