iTunes Custom RSS Tags – Author

The Author tag is either the name of your podcast or your name, depending on the type of theme for your show. If you are the sole host of the podcast or the star of the show, using your name makes sense. If you have a group effort, sticking with the name of the podcast keeps all the egos satisfied, while also branding the show as being a collective effort. The author tag is used both at the RSS channel level and at the item level. At the channel level, this is an all encompassing tag for the podcast as a whole. At the item level, author could be the same as the channel level author or it may designate a specific collaborator.
Based on these criteria, the Author tag will look like this:
<itunes:author>Your Name</itunes:author>
Or this:
<itunes:author>Name of Podcast</itunes:author>
