Chicago media and Chicago politics form two distinct gravitational centers in Mariano's top 10 — a grocery brand whose nearest audiences are defined almost entirely by local identity rather than by other grocery retailers.
The shape is two-peak. The first cluster is Chicago-specific magazines: Chicago Magazine at 0.94, Time Out Chicago at 0.94, and Chicago Reader at 0.93 sit at the very top of the set. Alongside them, WGN Morning News (0.92) adds a local TV dimension to the same neighborhood. The second cluster is Chicago-area politicians: Governor JB Pritzker at 0.94 and Mayor Lori Lightfoot at 0.94 score nearly as high as the magazines, forming a distinct civic-audience peak that runs parallel to the media one.
Below those two peaks, the scores drop noticeably. Rick Bayless (0.85), a TV personality, and Lou Malnati's Pizza (0.84), a restaurant brand, are the only food-adjacent neighbors in the top 10. ComEd (0.83) and The Second City (0.82) round out the set as a utility brand and a destinations brand, respectively — both Chicago institutions. No other grocery or superstore appears in the top 10.
The pattern is consistent: Mariano's audience shape is defined by Chicago civic and cultural engagement, not by grocery category membership.
