 * Target Books begins republishing selected novelisations with new cover designs by Alister Pearson. Other than the covers, these reprints are identical to earlier editions. A number of the reprints will be issued to coincide with video releases (which often used the same cover art) and rebroadcasts. The reissues are also in most cases retitled from their original publication, either with the "Doctor Who and the ..." title format being dropped, or the book's title being changed to reflect the original broadcast title. The first two novelisations republished in the new format are Doctor Who - The War Games and Doctor Who - An Unearthly Child.

 * After months of speculation, the BBC announces that it will not air a 27th season of Doctor Who in 1990, and at some point during the year the Doctor Who Production Office closes down. Although Sophie Aldred, in the later documentary More Than 30 Years in the TARDIS would say she was told the series had been cancelled, no actual public announcement of this is made by the BBC. Over the next few years the show's fate remains a matter of debate.
 * Around the time of the BBC's announcement, Virgin Books, which has purchased Target Books, announces plans to launch a series of original novels continuing Doctor Who from the events of Survival; the line is scheduled to launch in 1991. It is also announced that the traditional Target novelisation format would also come to an end in 1991, with all but a few stories left to be adapted.
