As you can see, the logo is more of a return to the classic, 1960s logo. But the insignia is totally new, with the "DW" initials fashioned to resemble the TARDIS.
To me it's a perfect way to freshen things up for the arrival of the eleventh Doctor, and his new show runner, Steven Moffatt, who had this to say:
The eleventh logo for the eleventh Doctor - those grand old words, Doctor Who, suddenly looking newer than ever. And look at that, something really new - an insignia! DW in Tardis form!
Simple and beautiful, and most important of all, a completely irresistible doodle.
I apologise to school notebooks everywhere, because in 2010 that's what they're going to be wearing.
The 1996 TV Movie:
It's okay. It is pretty much a direct recreation of an earlier logo, except it is more glitzy.
The Seventh Doctor Logo (1987-1989):
Wow, that's awful.
The Fourth, Fifth and Sixth Doctors (with minor revisions) 1980 - 1986:
It looks pretty godawful and 1980s now, but it worked for the time.
The Third and Fourth Doctor (1973-1980):
That's the iconic logo, also known as the "diamond logo". It's the logo, until the relaunch, that most people associated with the show. It's a little cartoony and cheesy now, but it still has a punch, especially when included in the "time tunnel" effect as see above.
The Third Doctor (1970 - 1972):
Cool, retro but timeless. This might be the most effective logo, which is why it is obviously the inspiration for the new one.
The Second Doctor (1967-1969):
The First and Second Doctors (1963 - 1966):
For it's time, this was rather cool. It had a modern, sci-fi sort of look without going over the top. It's clean and simple but still somehow conveys a space-age, mysterious feel.
So, what do you think of the new logo? Good, bad, or indifferent?
