A microblogging website founded in 2007 by David Karp. Noted for its ease of use, people can create short entries and post them in a matter of minutes. Four years after its inception, Tumblr eclipsed the well-known WordPress blogging site in number of users, and by 2013, more than 100 million Tumblr microblogs were hosted. The name comes from "tumblelog," which was a new term coined in the mid-2000s for a short-form blog. In 2013, Tumblr was acquired by Yahoo!.
Between X/Twitter and WordPress
Tumblr's huge popularity is due to how it fits into the blogging world. Entries can be much longer than X/Twitter posts, which are confined to 280 characters, but they tend to be smaller than standard blog entries that are often articles about a subject. A Tumblr entry can also be nothing more than a single image. See
