Pinterest, launched in 2009, is a visual social networking platform that allows users to share and curate images and videos through 'pinning' to themed boards. It rapidly grew to become one of the largest social networks, reaching over 11 million unique users within two years and introducing features such as business accounts and 'rich pins' to enhance user engagement and commerce potential. With strong consumer engagement, Pinterest is particularly effective for driving sales, attracting a diverse audience, and receiving notable awards for its design and functionality.
