Amazon.com launched a new advertising platform for mobile app developers to promote their apps on Android devices, Bloomberg reported.Developers can advertise their apps on Android smartphones and tablets, and also on Amazon tablets by paying Amazon each time a user clicks an advertisement displayed through the system, Bloomberg said.Campaigns for the service start at $100, the report said. Amazon could not be reached immediately for comments outside regular business hours.An earlier report suggests that Wal-Mart Stores is planning to test a new unlimited online shipping service this summer for $50 per year, a move that may hurt Amazon’s annual $99 Prime shipping service.Wal-Mart’s service, which will be by invitation only for now, will offer selected products on the company’s website to customers within three days or less, company spokesman Ravi Jariwala told Reuters. Wal-Mart offers more than 7 million products on its website.Amazon’s launched its $99-a-year shipping service called Prime, a decade ago with the guarantee of standard, reliable two-day shipping on online orders. Since then Prime has become the cornerstone of Amazon’s growth and the e-commerce company said U.S. Prime memberships grew 50 percent last year.With inputs from Reuters
