KEY OUTDOOR INC. has been a leader in the Illinois billboard industry for over 36 years. Local, regional and national advertisers have continually relied on our market knowledge to tailor and coordinate outdoor campaigns to their specific requirements.

Our History

Key Outdoor Inc. is a family-owned business operating in Central Illinois, Northeastern Missouri and Southeastern Iowa. Founded in 1977 in Kankakee, Illinois, the company now owns and operates approximately 1,700 outdoor advertising displays throughout its expansive coverage area.

We have always been growth-oriented, and we continue to build on our market coverage and client base. The flagship office in Kankakee soon became one of many offices, as the purchases of other major billboard companies were completed. The first addition to the Key group was the LaSalle-Peru market, followed by Decatur, Galesburg, Springfield and most recently the Quincy, Illinois market, which also includes parts of Missouri and Iowa.

We take pride in providing quality outdoor advertising at a reasonable price, having a knowledgeable and friendly staff, and maintaining solid relationships with our customers.

We welcome the opportunity to be of service to you.
