It used to be standard for the continuity announcer to make that kind of announcement over the end credits.

Does programme paperwork include a warning to pres that a programme includes a promo for the next episode so that somebody can review and decide how to proceed?

You get very little old school continuity like this anymore

Emmerdale was half an hour earlier on Tuesday, was it mentioned over the credits of Monday’s episode, of course it wasn’t

And then on the BBC, when Wimbledon over runs and a programme gets dropped, does the announcer mop that up telling viewers when it will now be aired, no they don’t, they just proceed with the next programme
