Yes, I thought it was pretty well known that the sponsor bumpers were recorded onto the programmes themselves at that time, there's been several cases across repeats of various programmes over the years of them not being edited out properly.

“Live” was probably a misleading word to use - what I meant was played out separately to the programme itself, ie. as a different “event”. 

I accept that programmes with a long-running sponsor like Corrie have the sponsor captions burnt on in post-production. But I don’t think this has always been the case. 

I did read somewhere - possibly referring to specific cases - that the sponsorship stings weren’t burnt onto the episodes in case a sponsorship changed or was withdrawn at short notice. There were cases when the sponsor was different in differing ITV regions (I think Emmerdale was example of this at one point), or on ITV2 omnibuses or encore showings. 

Sometimes a whole afternoon of programmes has the same sponsor which changes regularly and they wouldn’t necessarily know the sponsor (or have the up-to-date sting) when the various programmes were post-produced. 

I do believe some channels play them out separately - certainly the imports on National Geographic, which have random break points, and programmes like Neighbours and H&A on Channel 5. 

I’ve also noticed that some programmes on  ITVX and its predecessors don’t have the sponsor captions from ITV - and the EOP captions and end-captions are held long enough to know they aren’t just cutting away early. Corrie was an example of this, so perhaps a different edit is produced without sponsors?
