Many people publish a series of audio programs, called podcasts, through iTunes. Rather than streaming these programs over the Internet, users download them to a computer or mobile device like an iPod. Podcasts on almost any subject are available. You can download your favorite radio program, your church’s weekly sermons or a series of college lectures. Podcasts come as either audio or video files. Audio podcasts are in MP3 format. However, video podcasts are in MP4 format and can be put on your iPod. Tips Writer Bio
