Tumblr is a microblogging platform that allows users to post text, images, videos, links, quotes and audio to their tumblelog, a short-form blog. Users can follow other users, or choose to make their tumblelog private. The service emphasizes ease of use.
David Karp founded Tumblr in 2007 with Marco Arment as lead developer. 75,000 existing bloggers soon switched to the platform, and since that time, the service has garnered more than 3 million users. In 2009, Tumblr acquired the Tumblr iPhone app, initially known as Tumblerette, that was created by Jeff Rock and Garrett Ross.
