On November 23, 1963, at 5:46 PM, BBC aired the first episode ever of Doctor Who. Nobody figured that 59 years later, the TV show would still be relevant.
Now, to be sure, the show has not been on for 59 years. In 1989, the 26th season of the show ended. From a London policeman walking in the fog outside 76 Totter's Lane on November 23, 1963, to The Doctor and Ace walking in the sunshine across a field, 26 years and 13 days had passed.
The show was canceled, and would remain so for years.
A 1996 TV movie made by Universal and BBC failed to be picked up as a series. On March 26, 2005, BBC aired the first episode of the revived series. Initially, it was considered to be a reboot of the series, but it developed into a continuation instead, with all previous episodes as part of the same canon.
The show was a worldwide hit, and reached its peak popularity during David Tennant's time as the 10th Doctor, and began to taper off during Matt Smith's 11th Doctor and Peter Capaldi's 12th Doctor, bottoming out during Jodie Whitaker's 13th Doctor.
There are fans that only like the original classic Doctor Who. There are fans that only like the newer series. There are fans that like both.
So, how does one watch Doctor Who? Well, that depends on which version you want.
Classic Doctor Who episodes -- all that exist, which is another story in itself -- are available on Brit Box. Additionally, some free ad-support television (FAST) services carry streams of Doctor Who. This includes Pluto TV, Xumo, Plex, and Roku Channel.
The revived series is available on HBO Max. Next year, new episodes will debut on Disney+, but for now, HBO Max is your home for NuWho.
Whichever show you like -- classic, new, or both -- you have options when it comes to inviting the Doctor and his TARDIS crew into your Streaming Life.
