# Pinterest

Pinterest is a web and mobile application company that offers a visual discovery, collection, sharing, and storage tool. On the site, the users can create and share the collections of visual bookmarks.

The main axle behind Pin interest was this mobile shopping app which was launched in 2009 called Tote. It had the aim of making shopping faster, easier and more fun by giving people the tools to do some window shopping on their phone. But back then, the mobile shopping was still not popular and they couldn’t succeed that time.

So this is where the Pin interest picked up from and earlier this year the visual social network was valued at $5 billion after raising a $200 million Series F funding round.

# Flickr
