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.[5]

Features

Tumblr's emphasis is on customization and ease of use, with a relatively simple sign-up process. There are many forms of content that can be added to the user's own tumblelog; the seven general categories for posts include Text, Photo, Quote, Link, Chat, Audio, and Video. Users "follow" other tumblelogs, much like on Twitter, and their updates appear in one stream on the Dashboard. This is the interface from which users can like and reblog posts, as well as add content to their own tumblelog. The "like" button lets one user tell another that they like his or her content, and the "reblog" button easily reposts content from one tumblelog onto another, providing positive feedback.

Many Tumblr users take advantage of the queue feature to post frequently, which allows users to save and schedule posts to automatically send in intervals decided by the user. Tumblr advertises it as "an easy way to keep your blog active and consistent." [6]

On March 15, 2010, the Tumblr staff blog announced that they were testing a feature that would allow direct video uploading.[7] Previously, Tumblr could only host videos provided from an external host. Also, it recently added a feature that allows bloggers to add pages to their blog, allowing for more variety, organization, and flexibility with content.

History

David Karp founded Tumblr in 2007 with Marco Arment as lead developer.[8][9] 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 that was created by Jeff Rock.

On March 17, 2010, the Tumblr staff blog announced that Tumblr is now accessible on BlackBerry smart phones via an app created by Mobelux. On April 17, 2010, the application was made available on BlackBerry App World.

As of January 7, 2011 Tumblr included more than 2.6 billion total posts and nearly 12 million total blogs. [10]

According to a March 8, 2010 post by David Karp to the Tumblr staff blog, the site is now averaging 2,000,000 posts and 15,000 new users every day.[11] As of 2009, Tumblr had an 85% retention rate,[12] compared with 40% for Twitter.[13]

In September 2010, Marco Arment left Tumblr to focus on Instapaper.[14]

On December 5, 2010, Tumblr was inaccessible for about 24 hours due to errors during maintenance[15][16]

Recognition

In January 2009, Tumblr named to Obama's Top 5 Tech Tools in PC World.[17]

In August 2009, Tumblr's CEO, David Karp, was named Best Young Tech Entrepreneur 2009 by BusinessWeek.[18]

In August 2010, Tumblr was named Finalist in Lead411's New York City Hot 125.[19]

Finances

Tumblr's original funding came from Karp's earnings as a software consultant at parenting site UrbanBaby. Tumblr has raised funding from Union Square Ventures, Spark Capital, Betaworks and Sequoia Capital (among other investors).[20][21] Tumblr shares two lead investors with Twitter. John Maloney was the maker of UrbanBaby with wife Susan Maloney.
