Take Amazon Prime, mix it with Pinterest and add a dash of Instagram. The result is Amazon Spark , a new shopping-focused “social network” aimed at getting hardcore Amazon users to spend even more money with the e-commerce giant.
The service launched publicly on Tuesday on Amazon’s iPhone app, although it’s already chock full of posts, so the company has clearly been testing it for a while. It’s only available to Prime members, who pay $99 a year for free shipping, streaming videos and other perks. An Android version is planned.
