What is WordPress?
WordPress is the world's most popular content management system (CMS), powering over 43% of all websites on the internet. Created by Matt Mullenweg and Mike Little in 2003, WordPress began as a blogging platform but evolved into a full-featured CMS capable of running any type of website.
WordPress's success stems from its ease of use, extensive plugin ecosystem (60,000+ plugins), and flexibility. From personal blogs to enterprise websites, e-commerce stores to news portals, WordPress adapts to any use case. The White House, BBC, TechCrunch, and Sony Music use WordPress.
The platform consists of WordPress.org (self-hosted, open-source) and WordPress.com (hosted service). WordPress 5.0 introduced Gutenberg, a block-based editor transforming content creation. The REST API enables headless WordPress architectures with modern frontends.
