Doctor Who designs

Okay, I am a huge Doctor Who fan. The simplicity of the logo and the easily recognizable "Tardis" police box. In terms of Graphic Design, the show has created a massive amount of recognition from the font used for the two words "Doctor Who". They also don't stick to one version, for over 30 years Doctor Who has kept a classic vibe in most of their advertisements. I feel that the BBC has a certain "style" that is recognizable when seen versus an American counterpart.
My sister and I are definite BBC fanatics and I think you should be too!
