Wether shopping channels went off air or not it wouldn’t affect the sales, not with a website that’s open 24/7.
I noticed Highstreet TV and the other pre-recorded channels stayed on too. QVC never went off when Princess Diana died and although she had the HRH title taken off her, she really was “the peoples Princess” I’m not a Royalist and I wasn’t keen on Prince Philip due to his killing tigers, shooting Grouse and his love of stag, deer and fox hunting, which to be honest I was surprised how much the BBC of all places went in on, not to mention how he spoke to people, but he was someone’s husband, father and grandfather and I’m sorry for their loss.
Just edited to add stag and deer, I forgot to put them in.
