From Tardis Wiki, the free Doctor Who reference

I have read the TARDIS#Behind the scenes, and will now reference back to the Forum:Artifacts or Artefacts of Rassilon? where the ruling was that we would use the spelling that appears in more sources. Returning to the TARDIS#Behind the scenes, yes it does say that the World Distributors, Radio Times and Oxford Dictionary used the lower case Tardis.

In print only Virgin Books, BBC Books and Big Finish all write TARDIS in upper case. Then there's DVD blurbs, BBC media releases and various other promotional material that has been generated over the past 20 years.

There are, I believe more examples of different ranges etc using the upper case TARDIS than the lower case Tardis.
