A podcast is a type of online content that usually comes in the form of an audio or video podcast. It can be set up like a radio show, just one that is pre-recorded. Podcasts are usually regular occurrences and part of a syndicated series. Other examples of podcasts are recorded radio shows that stations upload online for listeners, they can be instructional media meant to help people, and there is really no limit in what you can use to produce a podcast. If you go to iTunes and search podcasts, there are literally thousands of podcasts from all different networks, industries, businesses, and people. You can search for these podcasts by just using a keyword to narrow your search.
