My fave in Québec is 'baladodiffusion' for podcast. Not sure if they say that in France too.
I love how Quebecois are always inventing these funny french words, always put a smile on my face.
I got to talk to my friends about 'baladodiffusions' but I'm not sure that they all know what a podcast is so I doubt they will appreciate this new word to its full extent.
I had no idea since nobody I know ever mentioned podcasts to me. Maybe they're all Luddites or they hide their podcast addiction well ;-) Me I exclusively listen to audio books (and I can recommend wholeheartedly the ones from Graphic Audio).
