What these products have in common is that they offer need-based media solutions with a low CPM (Cost Per Thousand Impressions) compared to other digital signage media.

Need Based Media
Studies show that 58% of all airline passengers and 68% of frequent flyers recall noticing a traditional advertising display at airports. This is just one example of the limitations of standard outdoor advertisement and digital signage solutions. Our need based media solutions aims to integrate digital advertising into information displays which increases this awareness up to 100%.
