When Doctor Who returns for a full thirteen episode series five in 2010 practically everything will be changed. New Doctor, new companion, new production team, new TARDIS exterior and rumors abound that the TARDIS interior and the show’s title music will also be different. The BBC added one more change to the pile today with the unveiling of the new logo design, as seen below. This may also indicate that the entire title sequence will, well, change! Check out the new logo that will usher in the reign of the eleventh Doctor and, below that, take a look at a showcase of the other logos over the last forty-six years.

About the new logo Steven Moffat, the new Lead Writer and Executive Producer said:

“A new logo. 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.”
