History of the Doctor Who Universe
President John F. Kennedy is assassinated by James Stevens, a journalist who has travelled from the future using a time ring. Stevens is the long-rumored "man on the grassy knoll," who has murdered the President to thwart the Master's plan to sabotage Earth's history and create a timeline in which UNIT and very possibly the Third Doctor never existed. ("Who Killed Kennedy")
 * The Ninth Doctor is in the crowd watching President Kennedy's motorcade drive by in Dallas just before the President is assassinated. A photograph which shows the Doctor among the spectators later finds its way into Clive Finch's collection of files about the Doctor ("Rose").
