 * According to some accounts, a Cybermen invasion of London was attempted this year, which was thwarted by the Doctor in his first adventure with UNIT after its formation. (DW: The Invasion) Due to the UNIT dating controversy, the exact year of this event is a matter of debate; this listing is included based upon the reference in The Sound of Drums that UNIT existed in 1968, while The Invasion established that it was a newly formed organization at the time of the Cybermen invasion.
 * UNIT establishes protocols for first contact with alien life. (DW: The Sound of Drums) This may be as a consequence of the events of The Invasion
