An anonymous reader writes: Workers in New York City have begun installing the city's first LinkNYC kiosks. The kiosks are free, public Wi-Fi access points, which are taking the spots formerly occupied by phone booths. 500 more of these hubs will be installed by mid-July, and the full network will eventually include over 7,500 of them. "Once completed, the hubs will also include USB device charging ports, touchscreen web browsing, and two 55-inch advertising displays." The displays are expected to bring the city $500 million in revenue over the next 12 years. When the project was announced in 2014, officials said construction would start "next year." They sure cut it close.
