It would seem stv adverts failed or itv forgot to inform stv about the adverts.
Actually STV went straight from the horse racing to tipping point without adverts.
Then after the STV ident it went straight to a blank itv caption card with no mention of the breakdown on the card.
Then STV went to there fault caption card and it stayed like that for over 4 minutes with no announcer saying sorry for the break in programmes at all.
Then STV sorted out the problems and showed tipping point like normal.
I do have video of it and I will upload it soon
That's TV and Local Television Ltd are the Carlton and Granada of local tv
