This is one of my favorite guerrilla marketing videos, surprisingly done by Google. It captures what makes guerrilla marketing great: a simple, yet highly creative idea that engages people because it’s FUN and without pushing any particular message.
Taking part in social media is somewhat similar in that you sometimes have certain conversations with people because you (and they) truly enjoy building relationships and getting to know people that are working in other fields, living in other countries, and interested in different things.
What about you? What are your favorite examples of guerrilla marketing?
