 In 2006, responsibility for running the fair was delegated to the Oregon State Parks and Recreation Department, and the division is now known as the Oregon State Fair & Exposition Center (OSFEC), which holds events on the fairgrounds year-round.As Oregon agriculture expanded in the early 19th century many communities formed agricultural associations for the purpose of sharing information on farming practices and resources.These groups began to organize county fairs such as the Yamhill County Fair (1850).
