Now the question is, who identifies their podcast as "asia?" It seems like on awfully broad topic to me - the hugest continent in the world. Unless, of course, some of these podcasts are geography podcasts, that are literally about asia. But I supect that many are actually simply podcasts from asia, that have chosen not to define themselves in any way narrower than that. And there's another definition of Asia even bigger than the continent. Many people who are generally called Asians, aren't from Asia at all! So you might hear in this category podcasts from Seoul Korea, or from China, or Japan or Singapore, or Mongolia, or, for that matter, Mother Russia herself.
