Smart TV TVs connected to internet ("Smart TVs") were a too good opportunity for advertisers to track the behavior and usage of their users/customers. On Samsung's own website we can read: Samsung Smart TVs have built-in Automated Content Recognition (ACR) technology that can understand viewing behavior and usage including programs, movies, ads, gaming content and OTT apps in real-time. It’s a simple 3-step process: 1. Let us know the brand and title of the commercial spot you would like to target for your TV Ad Retargeting campaign. 2. The selected commercial is recognized and instantly matched with our ACR data.
