Amazon Prime Accounts Are Exploding In Popularity, Now Up To 16.7 Million

Amazon has 16.7 million Prime subscribers, according to a new research report from Consumer Intelligence Research Partners (CIRP).

According to CIRP, this is up from 9.7 million a year ago. It also says that 93% of Prime subscribers are happy with the service and plan to stick around for another year.

CIRP got its numbers through a survey of 300 Amazon.com users.

Prime is $79-per year service that gives users free two-day shipping, as well as access to Amazon's Netflix-like video streaming service. It's a pretty good deal for anyone that uses Amazon frequently.

Amazon Prime members spend "$1,340 per year, compared to $708 per year for non-Amazon Prime customers, and account for 56% of US product sales," says CIRP in its press release on the findings.
