The definition of what an advertising agency is has certainly changed over the years, but one truism remains – agencies exist as a collection of experts who use their professional advice and talents to advance their clients’ brands and messages. These talents are used in print advertising, graphic design/collateral, radio and television production, public relations, sales promotions, events, outdoor displays, web and digital media. Agency sizes vary and our goal for this list is to recognize as many St. Louis communications professionals as we can.
We’ve attempted to gather the names of St. Louis advertising agencies from over the years. Some of these firms were headquartered in St. Louis, while others had their headquarters in different cities and maintained a St. Louis office.
In any list of this nature there are omissions and we apologize in advance. If you know of an advertising agency that is not included please send it via email to email@example.com. If you can include a brief history (or archives) we would appreciate that information as well.
