Big fan of The Guardian's Media Talk about UK media. (Latest episode: http://bit.ly/MediaTalk2010-06-10 (MP3)). The UK is so similar, and yet completely different!
Other media podcasts:
-The Media Show (BBC iPlayer pop-up), iTunes Canada.
-NPR, On the Media (iTunes Canada link) (Latest show (MP3) is extremely good)
Any other suggestions (in English or French) ?
