Pinterest is a website that allows users to share photos, allowing them to create image collections and arrange them by themes, like events, interests, hobbies, and others. The site uses a pinboard style design and users can browse other users' pinboards. Users can also "pin" images from other pinboards into image collections, as well as "like" images from other users.
Pinterest was founded by Ben Silbermann and launched in March 2010 as a closed beta. Cold Brew Labs manages the Pinterest site. In March 2011, an iPhone app was introduced, helping to increase the usage of the Pinterest site. Time magazine included Pinterest in its list of the "50 Best Websites of 2011" article on August 16, 2011. By December 2011, Pinterest was getting 11 million visitors each week. The site was officially made available to everyone on August 10, 2012, with no invitation required to join. Apps for Android OS and the iPad are also available.
