E! News Video (0.83) and App Store (0.83) sit at nearly identical heights atop Apple Books' neighbor set — two distinct poles that define a two-peak audience shape.
The first peak is entertainment and celebrity media. E! News Video at 0.83 is the single strongest pull, and it is a News Publisher, not a fellow Entertainment Platform. ABC News (0.74) reinforces the news-publisher thread, while Bitcoin Magazine (0.80) and What's Trending (0.74) add a magazine and a website to the media cluster. The second peak is finance and technology. App Store (0.83) and Invesco US (0.83) are separated by just 0.0003, and E*TRADE (0.82) sits just below them — three Finance or Technology brands bunched tightly together. GEICO (0.75) and Audi (social) (0.75) extend the brand-heavy side of the cluster.
Only one neighbor shares Apple Books' own subcategory of Entertainment Platforms: Apple TV at 0.72, the lowest-scoring entry in the top 10. The audience shape is dominated by finance brands and news/media publishers, with the platform's closest sibling appearing only at the edge of the set.
That combination — investment and trading brands on one side, celebrity news outlets on the other — suggests an audience whose media habits span financial content and entertainment coverage, with the reading platform itself occupying a narrower slice of their attention than either pole.
