The packages offered will include not only Internet but "regular TV, the kind you could only get from your cable provider," as well as on-demand programs, Medin told the kickoff event.
Google said it was offering a full ultrafast Internet and television package for $120 a month, with waived installation fees and a free tablet. It also will offer Internet only for $70 a month.
It will also offer free Internet at the current speed of five megabytes per second but will charge an installation fee.
Google asked residents to register to determine the neighborhoods where the project will be introduced in Kansas City, Kansas, and neighboring Kansas City, Missouri.
It was not immediately clear when or if Google would expand the project to other US cities.
Google announced its plan to build an experimental high-speed Internet network two years ago, saying the United States had fallen behind other major nations in broadband speed and access. "Fast is better than slow. On the web, nobody wants to wait for a video to buffer or a website to load," Medin said.
