Google WiFi: Google announced Tuesday that it will be providing free WiFi to the Chelsea neighborhood in New York City — where the company has its own New York headquarters.

The tech giant announced its plans in a Tuesday morning press conference with Sen. Chuck Schumer and Google chief information officer Ben Fried. The effort makes Chelsea the first wired neighborhood in Manhattan and the largest continuous WiFi network in the city.

Google has also built a high-speed fiber network in the Kansas City metropolitan area, but Fried told press that the WiFi network is unrelated to that effort, CNN reported.

Panasonic also introduced a television with facial recognition technology at its preview event Monday — the device will be able to identify who’s watching a television and display customized content. Several privacy groups have raised concerns about the expanding amount of facial recognition technology in consumer devices, prompting the FTC to release best practices about the technology this past fall.
