I studied a handful of foreign languages in school, and I like to exercise them a little from time to time, even if I'm firmly ensconced in the monolingual desert of the USA. Podcasts are an excellent way to do this, and of course the iTunes store's podcast directory is a very easy way to get podcasts. However, the number of foreign langage podcasts there is rather limited.
Some time ago I visited some foreign iTunes stores, and tried to get some music from them, but this failed because apparently only people with credit cards issued in the locale of any given iTunes store can buy things there. But wait (I pondered) -- almost all podcasts are free! Credit cards won't even come into play. And yes, in fact, you can go to a foreign iTunes store and download as many podcasts as you like, exactly as you would on the US iTunes store, complete with auto updates.
So, if you want to extend your podcast listening and/or viewing to some new sources, I suggest that you go down to the bottom of the main iTunes store page where the store selector menu is, and try out some of the foreign stores. You won't be able to buy their music, but you can definitely check out their podcasts. (And if you are reading this from someplace other than the USA, then just substitute the name of your locale into the above; the hint should still apply.)
