How to turn off ACR on your TV (and why it greatly enhances your viewing experience)
Briefly

Smart TVs employ Automatic Content Recognition (ACR) technology to gather information on user viewing habits and transmit it to centralized databases. This data allows manufacturers to create targeted advertising strategies. In 2022, advertisers invested approximately $18.6 billion in smart TV ads, with expectations for growth continuing. ACR functions by capturing screenshots and cross-referencing them with media content. It can identify up to 7,200 images per hour, linking personal data with viewing preferences, while also raising concerns about potential exploitation of sensitive information.
These days, most popular TV models utilize automatic content recognition (ACR), a form of ad surveillance technology that gathers information about everything you watch and transmits it to a centralized database. Manufacturers then use your data to identify your viewing preferences, enabling them to deliver highly targeted ads.
According to market research firm eMarketer, in 2022, advertisers spent an estimated $18.6 billion on smart TV ads, and those numbers are only going up.
ACR can capture and identify up to 7,200 images per hour, or approximately two images every second. This extensive tracking offers money-making insights for marketers and content distributors because it can reveal connections between viewers' personal information and their preferred content.
The most disturbing part is the potential for exploitation. In the wrong hands, sensitive information gathered through ACR could be dangerously misused.
