Google Fiber recently announced plans to expand its gigabit fiber service to Mesa, Arizona and Colorado Springs, Colorado. Mesa approved Google Fiber's application in July, making it the first city in Arizona to get the service.
Jain told Reuters Google Fiber today is signaling that it is not planning to cover the whole of the US.
"There was an impression 10 years ago that Google Fiber was trying to build the entire country. What we are gesturing here is, 'No, we are not trying to build the entire country'," he said.
Google Fiber became part of Alphabet's Other Bets group in 2015 to offer investors more transparency about the costs of loss-making projects like X, which oversaw Project Loon and Google's autonomous vehicles, now called Waymo.
Jain said the group had to move from a "spirit and culture of tremendous innovation to one of operational excellence" and could not rely on "a rich parent's wallet."
