iHeartRadio's top 10 neighbors span entertainment platforms, film studios, TV channels, musicians, and tech brands — with no single neighbor pulling far ahead of the rest.
The shape is flat: scores run from YouTube at 0.93 down to LG USA Mobile at 0.89, a range of only four points across ten neighbors. That compression means no one entity dominates; the audience looks broadly mainstream rather than tightly clustered around a single kind. Tallying the subcategories across the top 10 confirms the mix: YouTube (0.93) and Universal Pictures (0.92) represent entertainment platforms and film studios respectively; FOX (0.91) is a TV channel; Samsung Mobile US (0.91) is telecommunications; Fergie (0.90) and Bruno Mars (0.89) are musicians; 20th Century Studios (0.90) is another film studio; and Windows (0.89), SEGA (0.89), and LG USA Mobile (0.89) cover technology and game development. Notably, no other Podcasts and Radio entity appears in the top 10 — the audience shape is defined almost entirely by cross-kind neighbors. Musicians and Bands (two entries) and Film Studios (two entries) are the most represented subcategories, but neither dominates.
The flat, cross-kind spread suggests iHeartRadio's audience is shaped by broad mainstream media consumption rather than loyalty to any single entertainment format.
