 It was established by Derek Webb and artists he knew after he became one of the first major label artist to give his album away for free digitally on his website, where over 80,000 free copies of the album were downloaded.
 He then used the mailing address gathered in to book shows and after attendance at his shows had increased dramatically he decided other artists could benefit from the same idea of giving away music in exchange for location and contact information that may be more valuable than money made selling digital albums.
