I have a feeling it’s more to do with ratings than ageism, there are plenty of younger presenters as well a older ones. When the ratings flag new blood often appeals to a wider audience. Also when we reach “retirement” age do any of us want to commit to a long series or several days a week, Attenborough comments on issues as an “expert” he is not a regular presenter. Brian Cox is much younger commenting on Astromomy, the BBC have biases but I dont think Ageism is one.
Women are a minority view so should be disregarded
