Doctor Who 50th Anniversary Special

[fajrdrako]

From Wired:

As of today Steven Moffat has confirmed that he is completing a script that will feature the current Doctor, Matt Smith, facing a foe so great that he will need assistance from all ten of the previous TARDIS inhabitants. That’s right, rumors say Eccleston is in!!! The producers have gotten agreements from all living actors who have ever played the Doctor; Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann, Christopher Eccleston, David Tennant, and Matt Smith. With some studio special effects they have even resurrected William Hartnell, Patrick Troughton, and Jon Pertwee.

I love the way they can bring them back from the dead. The Spiritualists of Arthur Conan Doyle's day would be so envious.

This sentence caught my attention:

Every decade since the inception of Doctor Who there has been some sort of anniversary special that pays homage to the previous Doctors.

Is that true? I thought there was nothing at all between the episode with the Eighth Doctor in 1996 and the Ninth Doctor in 2005.
