The company, founded by billionaire Jeff Bezos, said that faster service for millions more Americans would change "daily life for rural customers."

E-commerce giant Amazon is investing $4 billion with a focus on rural delivery expansion that will allow it to reach 4,000 smaller communities with same-day and next-day shipping.

Amazon.com is bringing its Same-Day and Next-Day Delivery to more communities in the U.S., extending the service to thousands of smaller towns and cities across the country.
