WordPress.com is a platform for self-publishing that is popular for blogging and other works. It is owned and operated by Automattic, Inc. It is run on a modified version of WordPress. This website provides free blog hosting for registered users and is financially supported via paid upgrades, "VIP" services and advertising. However, WordPress.com is a freemium product whereas WordPress.org is completely free.
The site opened to beta testers on August 8, 2005 and opened to the public on November 21, 2005. It was initially launched as an invitation-only service, although at one stage, accounts were also available to users of the Flock web browser. As of February 2017, over 77 million new posts and 42.7 million new comments are published monthly on the service.
Some notable clients include CNN, CBS, Sony, Fortune.com, and Volkswagen. WordPress powers 39% of the internet and Fortune 500 companies use WordPress such as Microsoft, Disney, Sony and more.
If the free plan is in use, readers see ads on WordPress.com pages, though WordPress.com claims that it is rare. On its support pages, WordPress.com says it "sometimes display[s] advertisements on your blog to help pay the bills". In order to remove the ads, users need to purchase Premium Plan that costs $8 a month. 
In August 2007, Adnan Oktar, a Turkish creationist, was able to get a Turkish court to block Internet access to WordPress.com by all of Turkey. His lawyers argued that blogs on WordPress.com contained libelous material on Oktar and his colleagues which WordPress.com staff was unwilling to remove.
