Back in 2009, Jason Sadler launched his project IWearYourShirt.com and became a walking billboard for companies around the world. He basically charged these companies to wear a t-shirt with their logo on it. Everyday he would wear a different shirt and promote it on social media and provided viral marketing for these companies. The prices went up from $1 on January 1st to $365 on December 31st of that same year. That year he made $70,000 alone wearing shirts and his success continues to increase. He’s estimated to have made 4 million from all his projects.
