Genesis of the Daleks is also notable for being the only time in the classic television series where the TARDIS does not appear whatsoever for two consecutive serials. Also notable is the fact that this is one of the only two Dalek serials in all seven years of Tom Baker's run on the show, the other being 1979's Destiny of the Daleks. This became the start of a practice throughout the classic series where most recurring enemies would see a significant reduction in the amount of encounters between them and the Doctor; the Daleks, to name an example, would only star in one televised serial during each succeeding Doctor's tenure for the remainder of the 1963-1989 run.
