context: The original logo used for the First Doctor (and briefly for the Second Doctor) was reused in a slightly modified format for the 50th anniversary special "The Day of the Doctor" during the Eleventh Doctor's run. The logo used in the television movie featuring the Eighth Doctor was an updated version of the logo used for the Third Doctor. The logo from 1973–80 was used for the Third Doctor's final season and for the majority of the Fourth Doctor's tenure. The following logo, while most associated with the Fifth Doctor, was also used for the Fourth Doctor's final season. The logo used for the Ninth Doctor was slightly edited for the Tenth Doctor, but it retained the same general appearance. The logo used for the Eleventh Doctor had the "DW" TARDIS insignia placed to the right in 2012, but the same font remained, albeit with a slight edit to the texture every episode, with the texture relating to some aspect of the story. The logo for the Twelfth Doctor had the "DW" TARDIS insignia removed and the font was subtly altered, as well as made slightly larger. As of 2014, the logo used for the Third and Eighth Doctors is the primary logo used on all media and merchandise relating to past Doctors, and the current Doctor Who logo is used for all merchandise relating to the current Doctor.
