BBC News at 10 / News Channel - Technical problems 20/06/17

Yes, any following live programmes would only be on BBC1 so would just wait for the schedule.

The nations often join/leave sports coverage such as snooker at the weekend when there's another sports event, like a local football or rugby match. They normally make it as clean as possible with either the commentator welcoming them or the announcer giving an update as to what they're joining

I know joining recorded content in progress occasionally happens in the US when live sport overruns but it seems very peculiar (at least from a UK audience's perspective) to crash into a sitcom or drama part-way through. As mentioned, over here that only tends to happen when the nations are opting back into live coverage late or on sports channels where world feed or overseas coverage is being joined following an overrunning previous event.

The approach to dealing with overrunning programmes depends on the situation - in this case there'd no problem with letting the schedule run a few minutes late all evening as the overnight news channel can be joined later without any issues. In BBC One's case, they have a live announcer to aid navigation and an on-duty EPG scheduler to update all the TV guides so viewers are kept updated.

In cases where a programme has to hit a certain on-air time later in the schedule (e.g. a live event or high-profile show), you'd drop a progranme - often the one that should've already started but not always if it's also an important one and there's something more expendable - and use short fillers to get up to the next item in the schedule on time whereever possible. If the overrun's not too big, some channels are happy to drop promos and even commercials to get back on track.

On rare occasions programmes can be shortened to get things back to time, either live shows or sometimes daytime shows like Bargain Hunt where 45 minute episodes can be replaced with 30 minute ones.

Exactly how this all agreed varies between broadcasters but there's a degree of forward planning with filler lists/schedules and contingencies and some on-the-fly discussions with schedulers and/or editors.

A couple of examples here:

I noticed the other day when there was a news special on BBC1, that they put out a 60 minute Bargain Hunt instead of the normal 45. Didn't know there was such a thing

Bargain Hunt has 60 minute episodes that are a combination of 2 standard episodes cut down and stitched together (I believe originally for broadcast at weekends) and a number of 'special' episodes that were always 60 minutes in length.

CBS This Morning's brief report:

I can't believe a BBC Technical problem can make the news in America.

Doesn't surprise me, anything that goes viral online will somehow get on mainstream news. 21st century, standard.

I guess the closest we get is BBC1 joining the News Channel overnight and crashing in part way through HardTalk.

HLN also covered it as one of their light stories on their morning show today.

Noticed last night with ITV inserting the Grenfell video before Corrie they were still running 5 minutes late at 9pm but News at Ten seemed to start on time. And by on time I mean actually at 10pm.

I get the feeling this will become one of those misremembered myths in years to come. It will be forgotten that 99% of viewers didn't see Huw sat there for four minutes, as it only happened on the News Channel. The papers have already gone down this road as obviously that output makes for a better story.
