At 0.9835, FIFA.com sits in a tier of its own — but the more telling structural fact is what fills the remaining nine positions: four individual athletes and three club teams, with no other sports league in the top 10.
The shape is two-peak. One neighborhood clusters around football's institutional layer: FIFA.com (0.98) and FIFA World Cup (0.95) represent the governing and event side of the sport. The second, larger neighborhood is built from clubs and players — FC Barcelona (0.96), Manchester United (0.93), and Real Madrid C.F. (0.93) on the club side; Gareth Bale (0.94), Cristiano Ronaldo (0.93), Neymar Jr (0.93), and Zlatan Ibrahimović (0.91) on the individual side. Similarity here measures audience composition, not thematic overlap — the fact that these audiences look alike reflects a shared follower profile, not simply that they cover the same sport. ESPN Deportes (0.91) is the lone non-football-organization entry, the only media channel in the top 10, bridging the two football neighborhoods through a Spanish-language broadcast lens.
The overall picture is an audience tightly concentrated within one sport's ecosystem — governing bodies, marquee clubs, and star players — with a single media channel as the connective tissue between them.
