Former CTO Marco Arment Development of Tumblr began in 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.
As no one had done so after a year of waiting, Karp and developer Marco Arment began working on their own tumblelogging platform. This launch came only two months after Tumblr announced it would be moving towards paid advertising on its site. The dashboard is the primary tool for the typical Tumblr user. It is a live feed of recent posts from blogs that they follow. The dashboard allows the user to upload text posts, images, video, quotes, or links to their blog with a click of a button displayed at the top of the dashboard.
Users are also able to connect their blogs to their Twitter and Facebook accounts; so whenever they make a post, it will also be sent as a tweet and a status update. Users are able to set up a schedule to delay posts that they make.
They can spread their posts over several hours or even days. Users can help their audience find posts about certain topics by adding tags. If someone were to upload a picture to their blog and wanted their viewers to find pictures, they would add the tag picture, and their viewers could use that word to search for posts with the tag picture.
Tumblr allows users to edit their blog's theme HTML coding to control the appearance of their blog. Users are also able to use a custom domain name for their blog. Tumblr also offered a "fan mail" function, allowing users to send messages to blogs that they follow. The feature was rolled out in a "viral" manner; it was initially made available to a group of users, and other users could receive access to the messaging system if they were sent a message by any user that had received access to the system itself.
The messaging platform replaces the fan mail system, which was deprecated. This made the respective content available internationally, since go90 is a U.

Tumblr Head of Sales, Lee Brown, has quoted the average ad purchase on Tumblr to be nearly six figures.
Users may opt out, and the service stated that a revenue sharing program would be implemented at a later date. For example, a chain letter scam in May affected , users. The message urged users to harm themselves and criticized blogging in general. In July , the system was modified so that users cannot remove or edit individual comments by other users when reblogging a post; existing comments can only be removed all at once. Tumblr staff argued that the change was intended to combat "misattribution".
In September , Tumblr changed how threads of comments on reblogged posts are displayed; rather than a nested view with indentations for each post, all reblogs are now shown in a flat view, and user avatars were also added. The change was intended to improve the legibility of reblogs, especially on mobile platforms, and complements the inability to edit existing comments.
Although some users had requested such a change to combat posts made illegible by extremely large numbers of comments on a reblogged post, the majority of users even those who had requested such a change criticized the new format.
