February

 * 15 - BBC Broadcasting Research issues its Television Audience Reaction Report for Season 24 of Doctor Who, which had introduced a new Doctor, Sylvester McCoy. The show's Appreciation Index is 60, down from 69 for Season 23. Troubling numbers in the report indicate that the new Doctor and his companion, Mel, are not popular with viewers, and fewer than half are interested in seeing further seasons of the series. Despite this, viewership has actually risen over the previous year.

First photographic cover since DWN: Doctor Who - Enlightenment some four years earlier. Canadian fans notice a substantial (but ultimately temporary) jump in the cover price of Doctor Who books (on the order of $2-$3) beginning with this release.
 * 23 - The musical group called The Timelords releases "Doctorin' the Tardis", a dance single built around the Doctor Who Theme and recordings by Gary Glitter, and with a Dalek voice featured, is released in the UK.
