First public version of WordPress 0.70 was released May 27, 2003. It started as a fork from B2 blogging software, and over the past 14 years, it has grown to most used CMS on the web.
Over the past 14 years, WordPress has grown from its B2 roots as a blogging platform and driven by the community, evolved into the fully fledged CMS software, with no signs of slowing down as it powers close to the 30% of all websites on the Internet. And, with the REST API, WordPress has opened new avenues for growth in the future.
I am not going to go through the history of the WordPress features, or screenshots to show you how WordPress evolved during this time, there are many posts on the internet doing that already. And they show amazing progress made with the interface, core features, security. And it is amazing to see how far the themes and plugins development have come, and how you can use WordPress for anything, from a simple blog to massive eCommerce website.
WordPress has changed my life for the better, and I know that there are a lot more other WordPress developers and users who can say the same. I only want to say how grateful I am to all the people involved with WordPress development, starting with Matt Mullenweg and Mike Little for forking B2 into WordPress, amazing development community for all the work put into each new version and to everyone using my WordPress plugins.
Happy birthday, WordPress, I wish you many more new versions and many more birthdays.
