1990 (production)


 * 31 August - With no plans for a twenty-seventh season in sight, the BBC closed the Doctor Who Production Office. John Nathan-Turner also officially resigned as producer at this time. (He had still been contracted as producer for another year after 1989.)
 * Around the time of the BBC's announcement that no twenty-seventh season would be commissioned, Virgin Books, which had purchased Target Books, announced plans to launch a new series of original novels continuing Doctor Who from the events of Survival; the line was scheduled to launch in 1991. It was 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.
