Tumblr is a microblogging platform and social networking website founded by David Karp in 2007. Development of Tumblr began in 2006 during a two-week gap between contracts at David Karp's software consulting company, Davidville (housed at Karp's former internship with producer/incubator Fred Seibert's Frederator Studios which was located a block from Tumblr's current headquarters).
Karp had been interested in tumblelogs (short-form blogs) for some time and was waiting for one of the established blogging platforms to introduce their own tumblelogging platform. As no one had done so after a year of waiting, Karp and developer Marco Arment began working on their own tumblelogging platform. Tumblr was launched in February 2007 and within two weeks, the service had gained 75,000 users. Arment left the company in September 2010 to focus on Instapaper.
On May 20, 2013, it was announced that Yahoo! and Tumblr had reached an agreement for Yahoo! to acquire Tumblr for $1.1 billion in cash. Many of Tumblr's users were unhappy with the news, causing some to start a petition, achieving nearly 170,000 signatures. As of May 1, 2016, Tumblr hosts over 292.7 million blogs. As of January 2016, the website had 555 million monthly visitors.
