No, it most certainly is not called "Dr. Who"! Way back when the show first started in the early 1960s, it was invariably billed in TV guides and listings as "Dr. Who". At the end of each episode, right there at the very top of the closing credits, the character himself was even credited as "Dr. Who" for the first ten or eleven years. And there's enough old photographic and film evidence to show that the program was almost always referenced on scripts, clapper boards, film canisters, internal memos, virtually everywhere as "Dr. Who" even from a production perspective. But the program itself has never been known on screen as Dr. Who. Every single opening title sequence since 1963 has named the show "Doctor Who". If we can safely assume the name of the program in its own opening title sequence is the source of truth, then it's clearly not Dr., it's Doctor. So, dear non-fan, please be sure to take a note of this: it's definitely Doctor Who, it's definitely not Dr. Who. This detail could be more important than you know. That one small contraction could well mean the end of what might otherwise have been a beautiful friendship.
