Objective: Roll out a time-limited combo across city locations—fast. Solution: We deployed 12 LED screens with uniform templates and local price variants. Playlists used day-parting (breakfast/lunch/dinner) and a countdown slate. Process: Centralized CMS, on-site calibration, and a hotline for instant content tweaks. Results: Promo sell-through increased 22% vs. previous launches; the countdown boosted urgency and walk-ins near closing time. Takeaway: Consistent creative plus centralized control turns multi-site screens into one powerful campaign engine.
