Tumblr (stylized as tumblr.) is a microblogging platform and social networking website founded by David Karp and since 2013 owned by Yahoo! Inc. The service allows users to post multimedia and other content to a short-form blog. Users can follow other users' blogs, as well as make their blogs private. Much of the website's features are accessed from the "dashboard" interface, where the option to post content and posts of followed blogs appear.
