With the emergence of large multinational companies small and medium-sized enterprises have become increasingly difficult to keep up and record positive business results. If a long-term recession is added, it is no wonder the fact that a large number of small and medium-sized enterprises have had to withdraw from the business scene. For those who have somehow survived, as well as for new businesses that are just starting to look for their place under the sun, it was necessary to find a way to attract the attention of potential users of their products and services without having to allocate huge sums of money. Many have succeeded using method and tool of guerrilla marketing. Minimal investments with the maximum effect could have yielded results if they were accompanied by a great deal of originality, creativity, imagination, humor and innovation. Offering something new and different from traditional advertising methods, establishing and maintaining two-way communication with users has proven to be a very successful move. Achieving the effect of entertainment, sense of importance, surprise or even shock in people has created a desire to convey the experience further in achieving this and achieving the effect of spreading. Marketing message that costs a little, is quickly accepted by people, and the dream of every company is unstoppable. It is no wonder, therefore, that a large number of small and medium-sized enterprises now opt for geriatric marketing methods and tools.
