Slightly off tangent, but related to @WarrenTofficier’s last paragraph. I was randomly thinking about Telly Addicts the other day (quiz show presented by Noel Edmonds in the 80s, for you youngsters). Just wouldn’t work nowadays would it - very few tv shows or moments that the whole family sit around & watch together.
My kids say they “don’t watch tv”, by which they mean they only stream or watch stuff online. Their generation seem to be a mix of ‘stream whenever/wherever suits’, and ‘OMG I’ve got to be online at exactly x time because <insert social media person> is doing a live!!!’
If BBC want to tempt that generation to a Saturday night dancing show, seems quite a feat to balance that without alienating us core, ahem slightly more mature, audience.
