Notice: Spoilers are included for Doctor Who’s episode “Joy to the World.”
The long-running TV series Doctor Who might intriguingly exist as a fictional entity within its own universe, thanks to a whimsical hint in the 2024 Christmas special titled “Joy to the World.”Over the years, Doctor Who has earned a reputation for bending its own conventions, particularly with the return of Russell T Davies as showrunner. The recent 60th anniversary specials and Season 14 have remarkably intensified this self-referential approach, with clever allusions to iconic elements like the show’s signature theme song and characters—such as Mrs. Flood—who directly address the audience.
In the spirit of Christmas, “Joy to the World”largely tones down the self-referential antics, adopting a conventional narrative pace suitable for a family viewing experience after festive meals. However, this special intriguingly introduces a moment that blurs the boundary between reality and fiction. If interpreted as such, this could imply that Doctor Who exists as a television series within its own narrative, a revelation that could drastically influence the storyline for Season 15 and beyond.

One particular line stands out during the Fifteenth Doctor’s stay at the Sandringham Hotel with Anita. To cope with the absence of the TARDIS, the Doctor becomes fond of collecting miniature replicas of blue police boxes. When Anita questions this quirky pastime, the Doctor remarks about the prevalence of these models online, humorously stating they are ubiquitous “for some reason.”This line serves as a light-hearted nod to the very real TARDIS-themed merchandise available to fans.
In a scenario where Doctor Who never existed, it’s improbable that such models of vintage British police boxes would crowd the internet marketplaces—highlighting the Doctor’s bemusement. Steven Moffat’s “Joy to the World”momentarily taps back into Doctor Who’s self-referential style by implying that the popularity of these TARDIS models is directly linked to the Doctor’s adventures, similar to their appeal in our reality. If this logic holds, it leads to the fascinating possibility that “Doctor Who”is more than just a show—it could be a franchise woven into its own story universe.
What once could have been brushed off as a mere throwaway joke gains substantial weight following the events of Season 14. The series has increasingly embraced its meta elements, featuring characters like Mrs. Flood—a devoted Doctor fan apparent in her emulation of past companions’ attire. This metamorphosis in tone makes the notion of a show about the Doctor living within Doctor Who’s narrative feel surprisingly feasible.

Another perspective on the proliferation of TARDIS merchandise online in the Doctor Who universe can be explored without fully diving into Russell T Davies’s fourth-wall antics. Season 1 introduced Clive, a character who made it his mission to track the Doctor throughout human history, along with others who investigated the enigmatic blue box’s intermittent appearances throughout time and shared their findings online. This theme was further developed in “Love & Monsters,”which introduced LINDA, an official fan club centered around the Doctor.
Since then, the online fan base dedicated to the Doctor has likely expanded dramatically, driven by the advent of social media and digital technology advancements. The abundance of police box models available on the internet today could well be attributed to in-universe enthusiasts—modern-day followers conducting research akin to Clive and the LINDA members tracking the Doctor’s legendary journey through time.
