Pinterest is a visual discovery and collection tool that allows users to organize content they find interesting or inspiring on virtual pinboards. It has over 150 million active monthly users, with 70% being female. Users can browse topics they follow, save images and videos to their boards by pinning them, and share or repin content from others. Pinterest generates revenue through advertising and promoted pins. While it is strong in content curation and driving traffic to external sites, Pinterest faces threats from easier content spamming and less personalized experiences compared to competitors like Instagram that focus more on photo sharing between friends.
