MWITA-XMO-2026-006 · Evidence B · P1
For 10 established CPG brands in two categories, online added mostly duplicated reach to TV; one TV exposure often increased sales, online-only effects were less consistent, and mixed TV-plus-online exposure showed no sales synergy.
What this does not establish
Observational opportunity-to-see is not randomized attention; European established CPG brands and scanner buying do not transfer directly to services, new brands or profit.
Counterevidence & uncertainty
Online can add reach without creating incremental sales synergy; reach duplication and sales response are distinct outcomes.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
