The podcast was initially conceived by Apple for delivering musical/audio-based content for the iPod. A podcast can be played from the website directly, or downloaded as an MP3 or similar format to be played on a computer or compatible mobile device. Typically, podcasts are distributed directly by the producer or podcaster, or are syndicated via a content delivery platform. Besides audio, podcasts can now deliver other digital media such as video, e-books and radio broadcasting. Podcasts are used for everything from news and entertainment to education.
