The paper, "Watching the Watchers: Privacy Analysis of US Smart TV Automatic Content Recognition," examined eight smart TV OSes across 12 smart TVs from 10 manufacturers (Amazon, Hisense, LG, Roku, Samsung, Sony, Supersonic, TCL, Vizio, and Westinghouse) to examine when smart TVs use ACR and how effective opting out of user tracking is.
