In answer to your question: No. (-:
It's not as narrow a window as you might think. The advert played for most of the rest of the decade, and went on to be parodied on comedy shows ranging from #TheTwoRonnies to #BeadlesAbout in the 1980s.
Sorry @hovisbakery but I have to buy Kingsmill bread because @Sainsburys Ely have decided they aren't making enough money from your bread and have taken it off their shelves.
@alisynthesis I think my favourite is that Ridley Scott directed a UK 1970's advert for Hovis Bread:

All credit to his talent, it is probably one of the top 5 most iconic adverts in British TV history, and that is from a country that produces some fantastic ads.
Although now I want to find the Michael Bay advert, I hope there are lots of robots!
