There's a thing on the BBC News website saying that that advert with the drumming gorilla was the highlight of the advertising world in 2007. Really? I mean, it was okay, but it wasn't anything special. And until I read the article I didn't have the faintest idea that it was an advert for Cadbury's, so it's really not achieved its basic aim, anyway.
The coolest adverts of the year have been those home-made-looking ones for some phone company, no idea which one, or that one with squillions of musical instruments all in a line playing a catchy tune. Which could be advertising toilet paper as far as I know. If I ever end up in charge of arranging an advert for whatever company I'm working for, I'll insist that it uses the brand name in a catchy, memorable slogan that's the core of the advert. And no drumming gorillas.
