I suppose it's just a talk show, but on the internet instead of tv/radio? Or is there something else that make a podcast different from a talk show?
it's a talk show. usually like the ones with long conversations. the reason it's called a "podcast" is because sometime around the year 2003 it was originally supposed to remind you of the ipod, which it also had nothing to do with. and the name stuck because it made so little sense
