The National Association of County Information Officers was formed in 1966 to bring together communications professionals who wanted to share and exchange information with other county public information officers across the United States. NACIO remains dedicated to improving the professional capabilities of its members through an active listserv, training webinars, workshops at national conferences and other means.

As an active affiliate of the National Association of Counties (NACo), NACIO works to promote the value of professional PIOs to county governments and also to promote a better understanding amongst the general public of the roles and responsibilities of county government. NACIO members serve as judges for NACo's annual National County Government Month contest, and NACIO experts present highly entertaining workshops on media relations best practices at the NACo Annual and Legislative conferences.

Each year, NACIO hosts its annual Awards of Excellence in Communications contest to recognize the best works of county public information officers and state association of counties communications staff. In addition to recognizing “Best of Class” and “Best of Show” winners, the competition honors a variety of communications projects that include public relations campaigns, brochures and publications, articles and press releases, videos and Internet/electronic innovations. The deadline to enter the contest, which is also open to non-NACIO members, is in May each year.
