Across the years, Doctor Who has racked up a number of "title drops" (when the name of the episode is said within the episode). Here is a compilation of all of them, from An Unearthly Child right up to Resolution.

Note: My criteria for a title drop is based off of individual episode titles when available. Overarching titles will only be used when no individual titles are present.

Note 2: To qualify, title drops have to be exact. For example, if the episode title is "The Daleks," a character simply saying "Daleks" does not qualify. Every word of the title has to be said in the same order.
