Doctor Who | 1963
The history and cast of the longest-running science fiction series in television history: In England in 1962, two BBC-TV department heads, Sydney Newton (Drama Head) and Donald Wilson (Head of Series and Serials), created "Doctor Who" as a program that would educate children in history and science.
The original concept was that of an old scientist who could travel through time and space via his time machine the TARDIS (Time and Relative Dimensions in Space). For purposes of audience identification, he was accompanied by his granddaughter and two teachers. The very first story found the Doctor and his companions traveling to Earth's past--to witness the "birth" of man.
The Doctor was depicted as an anti-hero, rather than the hero, because he was enraged with the two teachers who would meddle in his life. It was not until the next story, titled "The Daleks" (the Doctor's greatest nemesis), that the format changed to depict the adventures of a man who traveled through time and space to battle evil--and have a good time while doing it.
In later episodes, the Doctor is revealed to be a Time Lord, a being from the planet Gallifrey who travels, via his TARDIS, to the past, future, or present of various planets to protect their beings from the sinister forces of evil.
