I'm going only on memories here so this might not be entirely accurate.
Back when new Who was first announced, but no one had been cast, RTD gave an interview saying that the companion couldn't be just another screaming girly, twisting her ankle and asking 'what is it Doctor?'. In the post Buffy days a female character would have to be far more pro active, especially if the show was to appeal to a female audience. This interview was shown on Ceefax (the BBC's teletext service) with the headline "'Buffy' type companion for Doctor Who".
The next day a different channel, I think C4, carried an edited version on their teletext pages. The headline here read "RTD wants 'Buffy' for Doctor Who'.
And the next day, a third channel, ITV I'd guess, had an article entitled "Sarah Michelle Geller to play Doctor Who!"
