Penguin Random House's top 10 neighbors span book publishers, literary magazines, news outlets, and a food blog — no single entity pulls away from the pack, and the scores compress into a narrow band from 0.97 down to 0.96.
The shape is flat: similarity scores measure how closely two entities' audiences resemble each other in composition, and here the top 10 form a tight cluster with no dominant anchor. Six of the ten neighbors are fellow Book Publishers: Alfred A. Knopf (0.97), Simon & Schuster (0.96), Riverhead Books (0.96), Penguin Press (0.96), Random House (0.96), and Little, Brown and Co (0.96). The remaining four break from the publishing world entirely: Publishers Weekly (0.97) is a Magazine, Guardian Books (0.96) is a News Publisher, The Millions (0.96) is a Blog, and Farrar, Straus & Giroux (0.96) rounds out the publisher cluster. The non-publisher neighbors — a trade magazine, a newspaper books section, and a literary blog — suggest the audience shape extends naturally into literary media consumption beyond publisher brands alone.
The overall picture is an audience defined almost entirely by its engagement with the literary ecosystem: trade publishers and the editorial channels that orbit them form a single, coherent neighborhood with no outliers pulling in a different direction.
