Diet Coke's top 10 nearest neighbors span home goods, finance, food, TV channels, TV shows, sports teams, and a game developer — no single category dominates, and no other beverage brand appears in the top 10.

The shape is broad: scores run from 0.69 down to 0.63 with no sharp drop-off, and the neighbor set is genuinely mixed by subcategory. SC Johnson leads at 0.69 — a Home brand, not a food or drink — followed by CBS Tweet (TV Channels, 0.67) and Chime (Finance, 0.66). Kellogg Company (Food, 0.66) is the closest food-adjacent neighbor, and Zynga (Game Developers, 0.65) is the most structurally unexpected entry in the set. Rounding out the top 10: Detroit Pistons (Sports Teams, 0.64), The Path (TV Shows, 0.64), The Doctors (TV Shows, 0.64), Stouffer's (Food, 0.63), and Kmart (Department Stores, 0.63). That's four distinct brand subcategories, two TV show entries, one TV channel, one sports team, and one game developer — a cross-kind spread that is the defining feature of this neighbor set. Diet Coke's own subcategory, Beverages, has zero representatives in the top 10; its audience shape is not defined by other drink brands.

The breadth of this neighbor set — spanning household products, daytime television, retail, and mobile gaming — points to an audience whose attention is distributed widely across mainstream consumer categories rather than concentrated in any single vertical.
