LG smart TV privacy concerns rise over network scanning and audio

The allegations against LG highlight a growing tension between hardware-level data monetization and consumer privacy protections. As manufacturers increasingly rely on Automatic Content Recognition to track viewing habits across external inputs, they face heightened regulatory risks regarding informed consent and network security. This scrutiny extends beyond simple viewing data to the potential for televisions to act as entry points for broader home network surveillance. The industry must now reconcile aggressive data collection strategies with the legal frameworks governing communications privacy. Watch for Migliaccio & Rathod LLP to potentially file a class-action suit if the current investigation confirms unauthorized audio transmission.

LG's smart TV privacy controversy arrives amid a broader regulatory crackdown on connected television data collection. In January 2025, Texas Attorney General Ken Paxton filed a lawsuit against Samsung alleging its smart TVs collected viewing data without adequate consent, claiming the company's ACR technology tracked what users watched across all inputs, including external streaming devices and gaming consoles, and shared that information with third-party advertisers. The suit sought civil penalties under Texas's data privacy statutes and demanded injunctive relief to halt the alleged practices. That enforcement action established a template that other state attorneys general have since referenced when evaluating similar complaints against television manufacturers.

The business model under scrutiny relies on ACR data as a monetization layer for hardware sold at thin margins. LG's ad-supported platform generated over $1 billion in revenue in 2024, according to the company's earnings disclosures, with ACR serving as the primary mechanism for attributing ad exposure to specific households. The tension between that revenue stream and consumer privacy obligations has drawn attention from the Federal Trade Commission as well. In September 2024, the FTC issued a 6(b) study order to six smart TV manufacturers, including LG, Samsung, and Vizio, demanding detailed information about their data collection and sharing practices. The study specifically asked about ACR usage, cross-device tracking, and whether consumers received meaningful notice before their viewing data was transmitted to third parties.

On the technical side, the Gamers Nexus and Level1Techs investigation echoes earlier independent research into smart TV surveillance capabilities. In 2023, researchers at Princeton University's Center for Information Technology Policy published findings showing that ACR technology on smart TVs could fingerprint on-screen content with over 99 percent accuracy even when users connected external devices via HDMI. The researchers demonstrated that manufacturers could build detailed viewing profiles without any direct integration with the content source. More recently, a 2025 report from the Electronic Frontier Foundation documented how smart TV firmware updates had expanded network scanning capabilities on LG and Samsung devices, noting that televisions were probing local networks for devices that had never been paired or authorized by the user. These technical findings provide the evidentiary foundation that LG smart TV privacy practices like Migliaccio & Rathod LLP would need to demonstrate material harm beyond abstract privacy concerns.
