An investigation by Gamers Nexus and Level1Techs reveals that LG smart TVs can eavesdrop on viewers through built-in microphones and webcams, collecting personal data including conversations, location, and information about connected devices. The TVs' ACR system reaches 49 million sets in the US and grants LG access to hundreds of millions of secondary devices on the same Wi-Fi network, with potential use in political campaigns. LG denies the claims, stating voice data is only collected when explicitly triggered.
