Keep selling after the discount dies
Every FMCG brand knows the shape of the curve: promo starts, sales spike, promo ends, sales crater. P&G wanted to know whether DOOH could flatten the crater — sustaining Pantene's momentum after the discount disappeared, without spending another cent on price.
So they designed the question properly: not "did the campaign work?" but "what happens in identical stores when only the screens differ?"
Quotable, self-contained, sourced — Blindspot case data, June 2026
- Pantene (P&G) ran this campaign on Blindspot's self-serve DOOH platform; objective: post-promo sales retention.
- Measured outcomes — Headline result: +140% sales volume.
- Headline result: +140% sales volume, verified against campaign data rather than panel estimates.
- Booked the way every Blindspot campaign books: exact screens, exact hours, per-play pricing visible upfront, no minimums — the same model behind 30%+ savings vs traditional buys.
A controlled study, not a victory lap
Every participating store ran the same promotional pricing phase. When the discount ended, only select stores kept running Pantene's DOOH creative in the beauty and haircare aisles — the rest went dark. Same products, same baseline, same shoppers. One variable.
Blindspot's retail analytics combined sales data, location tracking, and campaign timing, so any post-promo difference between the two groups could be attributed to one thing: the screens.
Continuity, not a burst
This wasn't a launch spike play. Pantene's creative held its position in the aisles where haircare decisions actually happen, week after week — testing DOOH as a medium of continuity rather than a campaign firework.
The screens kept the brand present at the decision point precisely when the price advantage was gone — the moment most brands quietly lose the shopper.
The floor held
Measured store-against-store, with identical baselines:
The point isn't the spike — it's the resilience. Where screens stayed on, the post-promo crash largely didn't happen. Shoppers kept choosing Pantene at full price.

Presence compounds
Discounts rent demand; presence keeps it. For FMCG brands, the lesson is that DOOH isn't just a demand spike — it's a retention and recall mechanism that protects full-price sales when the promotional crutch is gone.
