15 February (production)


 * 1971 - Decimialisation occurred in the United Kingdom. Production paperwork naturally reflects this changeover, with budgets and other documents converting to new pence. Cover prices on Doctor Who related merchandise, such as Doctor Who annuals and toys appeared to have radically different price points from this point forward, even though the initial changeover kept the value of money stable. Countdown #1 — which was the new home for Third Doctor comic stories — published a few days later, becoming the first Doctor Who-related magazine to be sold entirely in new pence.
 * 1988 - BBC Broadcasting Research issued its Television Audience Reaction Report for Season 24 of Doctor Who, which had introduced a new Doctor, Sylvester McCoy. The show's Appreciation Index was 60, down from 69 for Season 23. Troubling numbers in the report indicated that the new Doctor and his companion, Mel, were not popular with viewers. Fewer than half were interested in seeing further seasons of the series. Despite this, viewer count actually rose over the previous year.
