Posted this in the wrong Who forum, so copying it here. A guy proposed that Who failed after Smith left because the huge female audience mostly switched off when they saw this older looking man appear (who did seem older than his 50 odd years too, without wishing to be rude but failing.) Anyway....I said....
I know the majority will know all this stuff but anyway....that's definitely the case for the majority. The 50th anniversary was a sensation in America, shown in cinemas over there rather than just the UK (and all around the world.) Merchandise was flying off the shelves (even Big Chief could flog expensive 1/6 scales quickly.) Displays in shops were gigantic, filled with just about every product one can think of. Dr Who has always had a small fanbase in America but Tennant and Smith, coupled with US Netflix just made the show explode. It was huge, and yes in part because of a whole new set of female fans. So many that at Cons etc it was 50/50 male and female.
One only need look at what happened when Capaldi appeared. It just starting dying quickly. First signs came with licensing for merch which fell off a cliff. Ratings began to fall from rather large to ever disappearing. Some argue it was the stories, but Smith's Series 6 and 7 were messes let's be honest. 6 didn't even make sense, but they remained hits. Capaldi, while he did suffer because Moffat was running out of ideas, one could still argue 8 and 9 were superior to 6 and 7. Stuff like Deep Breath were genius (ok, 10 was **** but the damage was done.) By the end of Capaldi Who was all but dead in America as well as almost every country in the world, and diminished in the UK (with again merch disappearing to nothing at all, even Funko Pops dumped it and they do EVERYONE, I'm expecting a figure of me to be coming out soon.)
Let's not touch too much of Jodie. Her era has brought the show in the States to infinitesimal levels and even further reduced in the UK. I will grant you her stories have been beyond appalling so people switching her off probably did because of that and her performance (plus who actually wanted a female Dr?)
I think we all know now, the secrets out, that the BBC was going to rest the show again, with Jodie regenerating, fading out and left there until any revival. Russell T Davies only stepped in because it was him or no one. Plus he was able to bring in big money from Disney so the show now has a bigger budget per episode than ever before, and that's because he's so well known and trusted as a writer and show runner. And of course he's woke, which Disney is, more than any other of the entertainment companies, so they'll be supporting more progressiveness, although I think RTD is too intelligent to go full on. For a start he's not an anti white racist.
It'll be very interesting to see what happens now, Is RTD going to prove that if you stay around too long you go from hero to villain, or is the show going to have a massive revival and follow the 20 year rule where previously massive shows can come back because of nostalgia. And I'm sure RTD, with such good taste in men, will be making sure there's plenty of eye candy, as well as making spin offs which cater for everyone. I have a feeling he's going to give Tennant a short series with Smith traveling together because he asked on Twitter during Covid why that hadn't happened yet.
Interesting times!
