Great commercials seldom appear on America TV. The country is too puritanical for risqu� ads, too ‘politically correct’ for cheeky ads, and the focus group-types of approaches through which Madison Avenue uses to test advertising concepts tend to blunt edgy ads. You instead need to watch European TV to see great TV commercials.
My overall favorite this year has been a British ad for Honda automobiles, which uses a chorus to replicate the sounds of a Honda Civic on the road.

You can also see the ad through Metacafe, which  features some clips from some other excellent English-language TV commercials.
