Since hosting its first archaeology fair in 2001, the Archaeological Institute of America (AIA) has organized 23 more fairs and informed thousands of people through this popular outreach activity. The AIA fair model brings together independent archaeological organizations representing a rich array of archaeological subfields to present their programs and resources to a local community in an interactive and engaging manner. The goals of AIA archaeology fairs are to promote a greater public understanding of archaeology, raise awareness of local archaeological resources, and bring together proximate archaeological groups with a shared outreach goal. In this article, the authors discuss how the AIA fair model was developed through feedback cycles that include evaluation, data analysis, reflection, and trial and error; how it evolved; and how it is spreading to other groups around the world. To date, 26 AIA local societies have hosted fairs, and the popularity of this program as an outreach event is increasing among other archaeological groups across the United States, as well as in Belize, Canada, Colombia, the Czech Republic, Iran, and Myanmar. This growth in popularity and implementation presents us with unique opportunities to collect and reflect upon data essential to conducting archaeological outreach around the globe.
