Pinterest

Launched in 2010 as a closed beta, Pinterest allowed users to gather, organize, and collect images referred to as “pins” by posting them on personalized pages called “boards”.  It was conceptualized in December 2009 by co-founders Ben Silbermann, Evan Sharp and Paul Sciarra, using concepts related to visual bookmarking. After the introduction of the iPhone app, it exploded in popularity, landing on Time Magazine’s Best Websites list a few short months later. After the launch of Pinterest Mobile and the iPad app, the site topped 11 million hits per week, jumping into the top ten social networking services. A short time later it was the fastest site in history to break the 10 million view mark. Pinterest continues to remain popular as of 2015, and is currently developing and introducing new features to the service.
