1999

Throughout 1999, much concern was raised on Earth over a feared computer glitch known as Y2K bug or the Millennium Bug. This had the potential to cause technological havoc as clocks changed from 1999 to 2000 (the "00" in the date being expected to cause problems for many computer systems). The concern ended up being unfounded, though not without some help from one, or possibly two incarnations of the Doctor. (PROSE: Millennium Shock)

New Year's Eve
On 30 December, the Seventh Doctor, en route to Gallifrey with the remains of the Master, was forced to land the TARDIS in San Francisco and was caught in the crossfire of a gangland shooting.

Several things happened on 31 December. The Seventh Doctor regenerated into his eighth incarnation after the surgery almost destroyed the regenerative process, leaving the Eighth Doctor suffering from post-regeneration amnesia. The Master took paramedic Bruce Gerhardt as a host and his first action was to murder Bruce's wife after she saw the Master's eyes and screamed. With the assistance of Chang Lee and Grace, opened the Eye of Harmony. Opening the Eye destabilised Earth's physics and the Master used it to begin stealing the Doctor's lives. The Doctor helped Grace put the TARDIS in a temporal orbit, draining the power from the Eye and thwarting the Master. After the Master killed Grace and Lee, the Master fought the Doctor and fell into the Eye. The TARDIS reversed Lee and Grace's deaths and closed the Eye.

Dave Young spent the entire evening trying to convince his girlfriend, Anji Kapoor, that the millennium would not actually begin for another year. Kapoor, for her part, thought this extreme pedantry meant their relationship was in trouble. This incident led to her insisting on New Year's Eve 2000 that the two of them spend 2001 doing "Wild and Spontaneous Things' —the result of which was the couple spontaneously going to Belgium in February 2001. There, she met the Eighth Doctor and began travelling with him. (PROSE: Escape Velocity)
