This is for my pre-adolescent kids who like listening to pop music (and for parents peace-of-mind not worry about content of lyrics).

I've just noticed this week that the internet radio stream for Radio Disney is blocked now. There's an automated message saying that it's unavailable for my region.

What's up with this? It's been available for years and I used to use it on my AppleTV. I noticed around Christmas that the Radio Disney iOS app got updated and stopped streaming at that time too.

There was an announcement last October, that Family Channel's website Family.ca was carrying the stream on their website. Would Astral Media be able to force online listeners to their ad-supported site?

iTunes isn't blocking Radio Disney. Radio Disney is blocking Canada.

or Canada is blocking Radio Disney.

If you believe that, you probably also believe that Pandora has been "working hard to expand its offerings outside the United States" for four years now.
