Now on the face of things, this seems an expensive marketing campaign especially for a small niche area of London but consindering the old adage, "I told two friends, and they told two more friends"? It, as most viral/guerrilla marketing tactics do, will ensure a "Probably" massive audience then and a highly effective marketing tactic. Especially as this has currently been posted all around the internet and now actually reached my blog!
I believe Carlsberg used the Saatchi & Saatchi, London, UK advertising agency for this campaign.
What are your thoughts? Expensive? Effective?
Here are some more Carlsberg TV adverts...
