Ads that ran for years, I'll start, any other suggestions?

Another one....

Bord Na Mona with the Marino Waltz.

Good shout

The Shake n’Vac advert. Began in 1979(I think) and I’m quite sure it ran well into the 90s. I seem to recall that a new advert was made at one point but such was the public outcry that it was scrapped and replaced with the old advert again.

Very good shout, that was one that ran and they didn't care that the fashion was about 10 years out of date.

I’ll be your dawwwg…

THAT Kit Kat ad.
