It’s Podcast. Not Pod-cast or Pod cast.

It’s Podcast.  Not Pod-Cast or Pod Cast.  Podcast, for better or worse, with Zune putting it on the main menu with it’s now revision, will be the word that is used for the medium of audio and/or video provided on demand and by subscription.  If those two agree, then that’s what it is.  I’m surprised, but that’s how it’s shaken out.

If you write Pod Cast, Pod-Cast, Pod-casting, or any other incorrect form of the term you automatically will be perceived as not knowing what you are talking about.  So just don’t do it.
