Tumblr

Founded by David Karp in 2007, Tumblr is a microblogging platform and social networking website that allows users to post multimedia and other content to a short-form blog. Users can follow other Tumblrs, as well as make their own sites private.

Tumblr’s main features include the dashboard, a live feed of recent posts from Tumblrs a user follows; the queue, which enables users to schedule posts; tags; and HTML editing capabilities.

Yahoo acquired Tumblr in June 2013 for $1.1 billion, and David Karp stayed on as CEO. As of June 2014, Tumblr hosted over 188.7 million blogs and received more than 83.1 billion posts.
