Home & Away's production model is vastly different to Neighbours'. Firstly, the lifetime deal with Channel 5 means they have a guaranteed international partner. Ben Frow would get rid of it if he could, no doubt about that. He's stuck with it, forever and ever.
Secondly, they're not as reliant on the British market; that said Home & Away does remain a big deal in Ireland where Neighbours MK2 still gets a linear broadcast.
And thirdly, it still does the numbers in Australia.
I don't think streaming works for open ended soaps. Normally a streaming show is a season of 8-10-12 episodes. A soap just keeps on going, and it becomes very easy to simply fall behind. I'm trying to keep up with the rerun of Eldorado and it's impossible; I'm already ten episodes behind U&Drama.
Also, it ended up behind a paywall. I don't mind paying to see The Grand Tour or Clarkson's Farm but who's going to subscribe to watch a daytime soap opera that had become deeply unfashionable?
The fact ITV didn't step in to rescue it last time (when they bid against Channel 5 in 2007 when the BBC first dropped it) tells you all you need to know.
It's had a good run. Let it rest.
