And it's been UNIT forever, so I don't get why they're upset about the association now... Doctor Who is iconic; they should be happy that they're related in the Who-verse. 3nodding
According to wikipedia:
Following the broadcast of the 2005 series, in his regular column in Doctor Who Magazine #360 (August 2005), new series executive producer Russell T. Davies explained that the real life United Nations were no longer happy to be associated with the fictional organisation, and the UN's full name could not now be used. However, the "UNIT" and "UN" abbreviations can be used, as long as it is not explained what the letters stand for. It is unclear how this affects UNIT appearances in the various spin-off media.
Yeah, it would be nice if they just didn't bother stating explicitly what U.N.I.T. stands for, rather than saying on-air "Unified Intelligence Taskforce". I hope that's the case. In any event, they weren't wearing the U.N. blue berets in their New Series appearances, so that's also distancing it from the U.N. (though, now that I think of it, the only time I ever remember them wearing blue caps was the McCoy story 'Battlefield').
You've got a point: it wouldn't be that big of a deal if they didn't explicitly state it. Just say 'UNIT' and the older fans will get it; gives the newer fans a chance to look it up in Classic Who.
