I notice the BBC Three MHEG during the day on Freeview has changed. It now has the BBC Three logo in the purple box. Except the purple box variation of the logo isn't used on the channel itself anywhere apart from online, ironically anywhere that isn't directly part of the BBC Three website.
BBC Three don't seem to think much of their audience. I can just about forgive them for the Twitter account name, but do they really need to spell out how to Google* "bbc three"?
