If you ignore that one night in May 1996 when Paul McGann lit up our screens, Who was in absentia for 16 years, but that doesn't mean that the BBC weren't looking for another sci-fi or fantasy hit to replicate the show's success...
This week's Friday Fiver takes a look at a few such attempts - not programmes like The Tomorrow People inspired by the show's original run, or series like Primeval and Merlin which launched in the wake of the new show's success.
These are the shows that tried - with varying degrees of success - to fill that Doctor Who-shaped hole in our hearts between 1989 and 2005.

A fun Saturday night series for all the family - a blend of action/adventure and science-fiction, with fast-paced plots and swish gadgets. Cancelled, then revived by the BBC. A set of spinoff novels from Virgin Publishing.
Doctor What? We're talking Bugs - Brian Eastman and Stuart Doughty's '90s tech thriller!
Crime Traveller (1997)
Looking again at Crime Traveller - a sci-fi series that aired on Saturday nights on BBC One and saw a maverick lead (Michael French) and his glamorous assistant (Chloë Annett) travelling through time to help the helpless - you have to ask... why didn't they just bring back Doctor Who 8 years early?
Another attempt at launching a fantasy series in a primetime Saturday night slot, the short-lived Strange starred Coupling's Richard Coyle as a priest-turned-demon-hunter and Samantha Womack (then Janus) as his 'companion'. Tom Baker even popped up in one episode as a blind priest.
Sea of Souls (2004-2007)
Breaking the pattern somewhat, Sea of Souls aired on weeknights, but there was something about the show's set-up that just screamed Doctor Who.
We had an enigmatic lead - played by 'Victory of the Daleks' actor Bill Paterson - investigating the paranormal with the help of two attractive companions, and the drama again has several ties to our favourite show - Phil Collinson produced the first series, before departing to work on Who itself in 2005, while Paul McGann and Peter Capaldi both played guest roles.
Of course, it wasn't just primetime that tried to fill Doctor Who's shoes during its absence. If you were looking for a family-friendly sci-fi series in the '90s, one of the best places to head was CBBC.
One of the best offerings from the junior Beeb at this time was Aquila, which - with its magical alien vessel, sci-fi antics, 25-minute instalments and cliffhangers - had a strong feel of classic Who.
An honourable mention goes to The Demon Headmaster, which also helped fill the 'scary-but-for-kids' quota during the 'dark years'.
