WordPress continues to dominate the global website landscape. According to W3Techs, WordPress powers 43% of all websites on the internet and commands over 60% of all websites using a known CMS. These numbers make WordPress not only the most popular content management system in the world—but one of the most influential software platforms ever created.

A Brief History of WordPress

WordPress launched in 2003 as a simple blogging tool and evolved into a fully open-source content management system supported by a global community of developers, security researchers, and contributors. Its flexibility, plugin ecosystem, and cost-effective open-source licensing are key reasons it continues to grow more than 20 years later.

How Other CMS Platforms Compare in 2025

While WordPress leads by a wide margin, the CMS landscape includes several major players. Using the latest 2025 usage data from W3Techs:

• WordPress — 60.7% CMS market share / 43.3% of the entire web
• Shopify — 6.8% (dominant in e-commerce, proprietary hosted platform)
• Wix — 5.8% (website builder with strong template tools)
• Squarespace — 3.4% (design-driven hosted CMS)
• Joomla — 1.9% (open-source CMS with a long history but declining share)

These platforms take different approaches to customization and ownership, but none approach the scale and developer ecosystem of WordPress.

Open-Source vs. Hosted Platforms (Why It Matters)

WordPress is open source, meaning its source code is transparent, editable, and maintained by a global community. You can host it anywhere, modify anything, and maintain full ownership of your data. Platforms like Shopify, Wix, and Squarespace are hosted solutions. They control the hosting environment, database structure, updates, and security layers. These platforms are popular for ease of use but lack the flexibility and long-term ownership that open-source systems provide.

Big-Name Brands and Celebrities Using WordPress

Some of the world’s largest brands, media companies, and artists rely on WordPress, further proving its power and flexibility:

• White House (whitehouse.gov)
• BBC America
• Microsoft News Center
• PlayStation Blog
• TechCrunch
• TIME Magazine
• NASA Blogs
• Sony Music
• Walt Disney Company
• Reuters Blogs
• Katy Perry
• Beyoncé
• Snoop Dogg
• The Rolling Stones

Security: Why WordPress Still Earns Trust at the Highest Levels

Security is often raised in discussions about open-source software. Ironically, WordPress’s open codebase allows for faster discovery and patching of vulnerabilities, backed by hundreds of security engineers worldwide. A perfect example of this trust: the White House website migrated to WordPress in 2017 during the Trump administration as part of a cost-efficient modernization effort. As of 2025, whitehouse.gov still runs on WordPress, demonstrating its viability for high-security, high-traffic environments.

Why Businesses Continue to Choose WordPress

Its open-source nature, plugin ecosystem, SEO performance, and flexibility make WordPress the leading choice for businesses, creators, media organizations, e-commerce stores, and government agencies worldwide.

AI’s Growing Influence on the CMS Market

AI is reshaping how content is created, optimized, and managed online. WordPress’s open ecosystem has allowed rapid integration of AI tools—SEO automation, content writing, performance monitoring, and security scanning—giving it a competitive advantage against closed platforms that can only adopt AI features at the pace determined by their corporate roadmaps.
