Eli Noam
Columbia University media economist and author of Who Owns the World's Media? (Oxford University Press, 2016), which built a national press/broadcast census of ownership concentration across roughly 30 countries (2008–2013 data) — a methodology since treated as the founding ancestor for cross-national media-ownership measurement. He matters to this vault as the explicit methodological baseline that a 2026 paper on AI-era news citation measures itself against: Carragher and Carley's "Who Owns Digital News, and Who Gets Cited" (arXiv:2610.40164) describes its own work as "translating" Noam's census methodology "to attention-weighted measurement of digital news," and reproduces his four-firm newspaper concentration ranking (ρ=+0.465) and his HHI ranking (ρ=+0.407) across the countries his original study covered.
