@JamieNemeth There are Broadcaster "OTT" services on so called "Smart TVs".
The smart human doesn't give the TV a WiFi password or ethernet cable. They report what TV channel and even any HDMI info, if available, if using an external source. As well as the obvious app usage etc. To multiple destinations. Mostly can't be disabled. Some even room sound or video.
Maybe some German stations still have Teletext on Digital TV.
At least 3 broadcast protocols replaced teletext on Digital.
