I'm certain there are a non-zero number of TVs that either attempt to auto-join popular wifi hotspots (xfinity/tmobile/starbucks/etc.) and/or have cellular connections for telemetry.

Thinking more on this I think a business opportunity in the future will be companies that design hardware stacks that can go in random appliances that can gather usage information in the name of telemetry.

I give it +/- 5 years before an OTS coffee maker at walmart phones home.
