DOmedia: a game-changer in out-of-home advertising

With a mission to simplify the buying and selling processes of OOH (out-of-home) media, DOmedia has spent roughly the last 20 years making that happen. The journey began when Ken Sahlin, who played a key role in launching Dynamic Media Group back in 2003, was approached by a friend who needed help selling advertising space on mobile trucks. The cumbersome and inefficient process sparked Sahlin’s idea of introducing technology to streamline the process of buying and selling OOH media.

With the help of Rich Langdale’s NCT Ventures team, DOmedia was launched with the goal of creating a more efficient marketplace for OOH advertising, with their entrepreneurial spirit and ability to both recognize and address inefficiencies in the industry leading to the platform’s success. DOmedia’s first acquisition was OOH Connect, a website with a similar vision of simplifying the coordination of alternative advertising media. They then acquired Buyers Guide to Outdoor Advertising (known as the “Green Book”), a print publication that listed out-of-home media properties across the U.S. DOmedia digitized and updated the listing, transforming it into a comprehensive database of OOH media sellers.

DOmedia also focused on creating tools to help automate the most tedious and least valuable parts of advertisers’ and media sellers’ lives. By meeting their clients where they were already operating, DOmedia was able to create a suite of tools that made it easier to buy and sell OOH media.

Today, DOmedia is recognized as one of the leading companies in the OOH advertising space. By automating the buying and selling processes, DOmedia has created a level playing field for all OOH media and has made it easier for small vendors to compete with larger players. Their innovative approach continues to inspire others in the industry to find new and better ways of buying and selling media.
