Social blogging and networking, founded 2007 by David Karp. Acquired by Yahoo! in 2013 for $1.1B.

Tumblr's short-form blog format originated in Anarchaia, founded 2005 by German student Chris Neukirchen. This blog later inspired Projectionist, a self-described tumblelog, founded by Marcel Molina and Sam Stephenson, which later inspired Karp.
