Forum:Triple Miracle Day broadcast dates: Why?

Before we get too far into the season, I wanted to ask about a trend that seems to be developing. We're putting the broadcast dates for the US, UK and Australia on  Miracle Day episodes. We don't elsewhere. Any particular reason for it? Is this a kind of British "grudge" against Americans for getting the world premiere? I don't see why it's insufficient in the infobox to say that the broadcast date for The New World was 8th July 2011, and leave it at that. After all, the BBC willingly' gave away global premiere rights to Starz.

And before you ask, no, I don't understand why Doctor Who (1996) has double US/UK dates in its infobox, when we all know that the global premiere was actually in Canada. That line of the infobox should be for global premiere dates only, in my view. Other dates can be given under story notes. 23:41:10 Mon 18 Jul 2011
