A survey of 11 television and streaming-device companies has highlighted how difficult it remains for viewers to understand what their screens collect and where that information goes. The Verge sent manufacturers 17 direct questions covering microphones, stored audio, viewing recognition and cloud transfers, then compared the answers as well as the companies that declined to respond.
The inquiry contacted Amazon, Apple, Google, Hisense, LG, Panasonic, Roku, Samsung, Sony, TCL and Walmart-owned Vizio. Responses varied considerably. Some companies answered in detail, some supplied partial statements rather than a clear yes or no, and Hisense did not respond despite repeated approaches. The exercise therefore offers a comparison of disclosed practices, not a complete audit of the devices or their network traffic.
One central issue is automatic content recognition, or ACR. Smart televisions can use the technology to identify material playing on screen, supporting advertising, audience measurement and recommendations. Manufacturers commonly provide a way to decline or disable ACR, but those choices can be buried among agreements presented during setup. Separate operational traffic may also continue after a user opts out of content recognition, making it important to distinguish ACR from other diagnostic or service data.
The answers also showed differences in how voice features operate. Amazon said microphones in standard Fire TV remotes work only while a physical button is pressed, while compatible hands-free televisions listen locally for a wake word and include a hardware control to disable the microphone. Apple said Apple TV 4K's always-on processor listens for the Siri wake word and that Siri can be disabled. Google said supported microphones remain in standby until a hotword or button press activates them, and that saving voice recordings to a Google account requires a separate Voice and Audio Activity setting that is off by default.
LG said voice recognition is opt-in and requires either a remote-button press or a supported hands-free wake word. It said wake-word detection occurs locally and audio is deleted when no wake word is found. Roku said its televisions do not contain built-in microphones, although some remotes do. Samsung said its embedded microphone listens locally for its wake phrase and its remote microphone requires a button press. Several other companies did not directly answer every voice question.
The comparison does not establish that every data flow is unnecessary or covert. Connected televisions need some information to deliver services, update software and respond to commands. It does show that consumers must navigate different defaults, terminology and control paths across brands. Clear answers matter because a television can observe viewing habits in a shared home for years, and because declining one tracking feature may not stop unrelated operational communications. The survey gives buyers a starting point, but independent technical testing remains necessary to verify how the published policies behave in practice.
