Doctor Who first aired on 23 November 1963.
- From a production standpoint, its origins go back to March 1962 when the BBC began work on a document outlining the feasibility of mounting a science fiction program. By July, it had been decided that a show based on time travel would be the best avenue to explore. By March 1963, a Saturday teatime slot had opened up for the Autumn of that year, and work began in earnest to develop the vague "time travel show" that had been proposed in 1962. Within a few weeks, the character of the Doctor, the basic idea of the TARDIS, and the title Doctor Who had been mooted. This was soon worked into a "series format document, and the program moved from the concept stage to the initial phases of production in the summer of 1963.
