A component of Crispin Porter + Bogusky's recent Ask.com multimedia effort, this teaser billboard/transit campaign, seen in New York, San Francisco and Los Angeles, attempts to get people asking about Ask --which used to be called Ask Jeeves, but as you can see here, Jeeves is dead. At any rate, "an algorithm is the central underpinning of a search engine, but it's a funny word that most people don't hear every day, if at all," says CCO Alex Bogusky. The campaign "is designed to introduce the concept of an algorithm at a high level and inject the word into the consumer arena -- we want to get people talking about the algorithm, wondering what it is, while also sparking additional interest in Ask.com and the overall concept of search." The teasers were eventually paid off with the addition of the Ask logo-infused "Ask the algorithm" tag, two samples of which are in the PDF.
