On August 25, 2025, the world celebrates the 34th anniversary of Linux, a free operating system that began as a hobby project by a 21-year-old Finnish student, Linus Torvalds. What started as a small project has now become the backbone of modern digital infrastructure, powering everything from smartphones to supercomputers.
What started as a hobby project by a 21-year-old student, Linus Torvalds, has become the backbone of modern digital infrastructure. His simple message on August 25, 1991, to a newsgroup, “I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones,” couldn’t have predicted its profound impact. Linux fundamentally changed how we think about software development and collaboration.
From its initial release of version 0.01 with just 10,239 lines of code, Linux has grown exponentially. The Linux kernel now contains over 34 million lines of code, with contributions from more than 25,000 developers worldwide. This collaborative development model adds 10,000 lines of new code daily, making Linux one of the most actively developed operating systems.
The early milestones were impressive, setting the stage for future dominance. By February 1992, the first installable Linux distribution, MCC Interim Linux, was launched, followed by the first commercial distribution in November 1992. By 1994, familiar distributions like Slackware, Debian, S.u.S.E, and Red Hat Linux had emerged, laying the foundation for today’s multi-billion dollar industry.
Linux has achieved complete dominance in high-performance computing, powering 100% of the world’s top 500 fastest supercomputers. Its impact on cloud infrastructure is staggering, with the operating system powering over 90% of public cloud workloads globally. Major cloud platforms from Amazon, Google, and Microsoft rely heavily on Linux-based systems.
Through Android, Linux has captured approximately 72% of the global smartphone market, reaching billions of users annually. Linux also commands a significant market share in server environments, powering 96.3% of the top one million web servers. The enterprise Linux market is projected to generate $14.4 billion in revenue by 2025, cementing its status as a foundational pillar of the digital world.
