Podcasts are digital audio or video files that are distributed over the internet for users to download to their devices. The term podcast originated from the combination of "iPod" and "broadcasting" as people could automatically receive new shows without visiting a specific website. Podcasts are used by news organizations to distribute additional audio content, by youth media groups to share youth perspectives, and by educational institutions for self-guided campus tours. Creating a podcast involves designing the topic and format, starting a blog, recording and uploading audio files, and publishing them for subscribers.
