Creative circle in Denmark did a write up of good advertising web sites in their monthly PDF mag, Brandnews #37. The article is written by Holger Wilcks and tells an amusing story of trying to find decent ad sites. We're pleased as punch even though the hyperlink didn't work. ;-)
short translation: "The old famous adcritic.com with all the latest advertising commercials is closed for all of those who don't want to spend a fortune to see it. Luckily, there is a cheaper alternative. Danish ad-rag.com has Scandinavia's largest collection of advertising commercials and costs but a symbolic sum charged via paypal."
