Guerrilla marketing is a very low budget way of promoting a company, series of products or services, or specific marketing campaign. Rather than use traditional forms of expensive advertising and promotions, guerrilla marketing instead leverages imagination, time and energy while utilizing word-of-mouth resources to get in front of people with a specific message. Guerrilla marketers rely on creativity and ingenuity to leverage unconventional forms of marketing to get people excited about a specific marketing campaign. Some guerrilla marketing tactics are more reliant on energy, like handing out flyers at a large public venue. While other forms rely more on ingenuity, like developing a fun Web-based game and emailing to everyone you know (this is also known as viral marketing) hoping that they will then email it to everyone they know, and so on. This form of marketing used to be deployed by only small business. But today even large corporations like Burger King utilize guerrilla marketing and viral video to create all kinds of excitement with people all over the world.
