A technology podcast is an episodic series of digital media files (often in audio and video formats). The term podcast, like netcast and weblog, can refer to both the medium and the content.
Podcasts can usually be subscribed to for free as a category on Apples iTunes music store or Google Play Music. A typical episode will generally last at least 20 minutes per episode with some episodes reaching up to an hour long. Podcasts now have more than 250 million listeners with over 33 million downloads and streams each month and that number is growing monthly.
