Companies are continually innovating new ways to connect with their customers and deliver targeted messaging. Some brands, like Kotex and Dunkin Donuts, have embraced and incorporated new technology into their ad campaigns.

Secret Reflective McDonald’s Billboard Takes Advantage Of Late Night Cravings

McDonald's was challenged with driving hungry, late-night motorists to their restaurants. To accomplish the task, the company created a billboard using reflective tape which, while seemingly blank during the day, would reveal a message during the night when car headlights shone on the board. The words "open all night" along with the McDonald's logo were used on the billboard to let motorists driving at night know that they can stop at the fast food chain at any time.
