MWITA-XMO-2026-010 · Evidence A · P1
A 400-person panel split evenly into unexposed, CTV-only, DOOH-only and combined CTV+DOOH cells found significant positive relationships for most prespecified attitude-to-media hypotheses, but evidence of CTV-DOOH synergy was inconclusive.
What this does not establish
Small brand/survey panel, unequal video versus static creative and attitudinal endpoints do not establish reach, actual purchases, sales or profit.
Counterevidence & uncertainty
Both media appeared effective on several surveyed outcomes, yet their combination did not yield conclusive synergy.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
