NASHVILLE (AP) - Google is bringing its ultra-fast fiber optic service, with Internet speeds at more than 50 times the national broadband average, to Nashville and three other metro areas in the Southeast.

In addition to Nashville, the company said it will deliver service to Atlanta, Raleigh-Durham and Charlotte. Google officials said five Western cities previously identified as finalists remain in the running for fiber down the line.

"We had four cities here in the Southeast that were ready to go," said Kevin Lo, Google's general manager for fiber services. "I want to be really clear that this is not 'no' to anybody for the other five metro areas."

The other five cities in the running are Phoenix; Salt Lake City; San Jose, California; Portland, Oregon; and San Antonio.

Google Fiber boasts that its service can download an entire movie in less than two minutes and that it has vast potential in bus iness, science and education.

Lo cited the example of a geneticist in Provo, Utah, who can download an entire human genome, or about 200 gigabytes worth of data, via Google Fiber in less than half an hour. That compares with 77 hours at traditional broadband speeds.

"The next chapter of the Internet will be written at gigabit speeds," Lo said.

Launched as an experimental project in 2010, Google Fiber is available in Provo; Kansas City, Missouri; Kansas City, Kansas; and Austin, Texas.

Google is hoping the competition will prod existing Internet service providers such as Comcast, Verizon Communications and AT&T Inc. to upgrade their networks so they can run at faster speeds. Google figures it would still benefit in that scenario if the improvements to rival networks spur more Web surfing.

Prices for Google Fiber are comparable to or below what most households already pay. For example, in the two Kansas City markets, Google Fiber charges about $70 per month for just high-speed Internet service, or $120 for an Internet and TV package.

Lo declined to say when the service would be available to customers in the new cities, but officials in Charlotte said they hope the work to be complete within the next two years.

President Barack Obama earlier this month urged greater access to faster Internet speeds as a way to create jobs and make local businesses more competitive in the global economy.

The president is calling for a repeal of restrictions on local communities creating their own broadband networks, a stance at odds with major cable and telephone companies that often provide Internet service with little competition.

Obama has also angered the industry by calling for new Federal Communications Commission rules that treat Internet service providers as public utilities.
