Why isn't it Indoor or Outdoor anymore?
What is the difference compared to the classic Indoor or Outdoor digital signage purchase model?
Payment is made only after the contact of the audience with the advertising campaign creatives. When there is no one in front of the displays, the advertising is simply not shown.
When paying for an audience, the cost of contact is more optimal than buying a share of the air.
The advertiser gets the right audience for the classical model of buying broadcast time but can optimize costs.
