I don't work in the theatre world, so don't understand their funding - I just attend occasionally and love it.
I have watched some filmed theatre performances online during lockdown and thought it worked well. Obviously, it's not the full on live experience, nor is it the big screen experience via cinemas, which I also enjoy. It is its own thing and I would pay to watch theatre performances at home on the telly or laptop. Would you?
Surely, this potential massive online audience could help them survive. I would however hope they'd keep the tickets really cheap. A fiver, and I might watch every week, so that's £250 that could have out of me annually, which is more than I spent on theatre last year.
