Guerrilla marketing campaigns differ from the familiar and rely on unconventional means. Instead of spending money, creativity is crucial.
An often used example is graffiti on sidewalks. The Seattle Art Museum (Seattle Art Museum) sprayed an indication of a current exhibition on sidewalks in Seattle (Seattle Weekly Blog).
The Zurich Zoo relies on viral marketing with a Youtube-Video in which an elephant falls off a bridge, because he does not live in the Zurich zoo.
