Initially conceived as a British family series based on historical and scientific events, "Doctor Who" evolved into a global television phenomenon and cult classic spanning the course of 26 seasons over 50 years, even after a lengthy hiatus in the '90s. The show revolves around a humanoid alien known as the Doctor, a Time Lord who travels through the universe in his TARDIS, a time machine and spacecraft.
