Pinterest is a social media platform where users can create boards to "pin" and organize images and videos they find interesting or inspiring online. It was launched in 2010 by Ben Silbermann and allows users to categorize pins across different topics like fashion, food, home decor and more. While publishers initially declined to meet with Silbermann about purchasing Pinterest early on, it has since grown tremendously to over 27 million unique visitors and is now valued at $1.5 billion, receiving numerous buyout offers that Silbermann has rejected.
