Koch Industries Inc. once again has the best-known brand in Kansas. That’s according to the sixth annual brand-power survey, released by Wichita-based RSM Marketing Services. The results were based off an online survey conducted earlier this month in collaboration with the Wichita Consumer Research Center. It asked 1,000 Kansans to name the three brands from the state they thought were the most well-known around the country. “Over the past six years, we’ve seen Koch Industries go from non-existent on our survey to holding the top spot the last three years,” RSM’s managing partner, Bruce Rowley, says in a press release. Many of the mentions are clearly referring to ‘Koch Industries,’ while others refer to the political activities of the ‘Koch Brothers.’” Aviation once again had a strong showing, including the continued addition of the Boeing Co. (NYSE: BA), which along with the likes of Pizza Hut, Coleman Co. (both founded in Wichita) and Frito Lay, remain brands still strongly associated with the state despite not being based in Kansas. Also in aviation were the Cessna and Beechcraft brands of Textron Inc. (NYSE: TXT) division Textron Aviation, along with the first appearance by Spirit AeroSystems Inc. (NYSE: SPR), all of Wichita. “This year it was exciting to see five brands make their first appearance in the Top 25,” says Mike Snyder, managing partner at RSM.
