The largest light blogging platform in the world and its creator, Tumblr was established in 2007. Tumblr, one of the most well-liked social networking sites for young people today, is a new medium that sits in between standard blogs and microblogs, focusing on both expression and sociability as well as on personalisation. Tumblr adapts the conventional blog format into a frivolous, stream-of-consciousness narrative with brief, to-the-point entries and wildly sporadic trigger points, such as images, videos, quotes, links, or even flashbacks. The popularity of Twitter has paved the way for new microblogging programs, even though Tumblr is not based on Twitter (it is based on "Tumblelogs" like projectionist or Anarchaia). Actually, Tumblr is a service that sits in between Twitter and more conventional. As of 2013, the website has more than 20 million users, and Tumblr claims it will continue to provide value-added features. To use Tumblr, you must create an account on the official website and launch a microblog that syncs to Facebook and Twitter in addition to supporting publishing on the platform.

Tumblr places a strong value on customization and usability. Seven different sorts of content can be added by users to their Tumblrs, and the "Dashboard," which serves as the homepage, displays all of their followers' changes. Tumblr offers an extremely positive user experience since 85% of registered users stick around, which is far higher than Twitter's 40%. Tumblr allows users to update their content on the site by uploading it there as well as via email, AIM chatbots, calls to Tumblr's phone number, and even tiny bookmarks. Tumblr now offers automated content sync to Twitter and Facebook. With support for English, German, French, Italian, Japanese, Turkish, Spanish, Russian, and Polish, Tumblr also offers multilingual functionality.
