Good points. However, on-demand streaming has changed people expectations around content availability. A weekly show on linear TV makes sense when it's topical (e.g. Countryfile or news-related), if it's a reality contest with a finale (e.g. Love Island, The Apprentice) or a prestigious drama with cliff-hanger ending.

Even the idea of TV channels makes little sense today unless those channels reflect a genre or theme (e.g. The Arts Channel or the Horror channel). I suspect most people in the UK would struggle to describe the purpose or differences between BBC channels. Streaming services (including iPlayer) reflect what probably makes sense to most people - the genre or theme of the programme. BBC linear channels are increasingly irrelevant.
