Pinterest is a visual discovery and bookmarking platform founded in 2010 by Ben Silbermann, Paul Sciarra, and Evan Sharp. It enables users to find and save ideas in the form of images, GIFs, and videos, which are organized into boards based on themes or interests. The platform is widely used for inspiration in areas such as fashion, home décor, cooking, and travel, and has grown into a significant player in digital advertising and e-commerce integration.
