Android: The Dominant Mobile OS
Zusammenfassung
Android began in 2003 as a startup building an operating system for digital cameras. The market vanished, the team pivoted to phones, and in 2005 Google quietly bought the company for at least $50 million — what one Google executive later called its best deal ever. When Apple’s iPhone redefined the phone in 2007, Google scrapped its BlackBerry-style prototype and shipped a touchscreen Android instead. Given away free to any manufacturer, Android did to mobile what Windows did to the PC: it became the platform everyone else built on. It now runs on roughly three out of every four smartphones on Earth — the most widely deployed operating system in history — yet “open” Android is also one of the tightest control points Google owns.
A Startup for Camera Software
Android Inc. was founded in October 2003 by Andy Rubin, Rich Miner, Nick Sears, and Chris White. Rubin — a veteran of Apple, General Magic, and the Danger Sidekick — first pitched Android as a smart operating system for digital cameras, connecting them to PCs and online photo storage. Within months the team saw the digital-camera market peaking while mobile phones exploded, and pivoted to building a free, open mobile OS that carriers and manufacturers could adopt without the licensing fees Microsoft and others charged.
Google’s Best Deal
In July 2005, Google acquired Android Inc. for at least $50 million, keeping Rubin and the core team. The logic was strategic, not immediate: Google’s business lived on web search and advertising, and its founders feared a future where a single company — Microsoft, or later Apple — controlled the mobile gateway to the internet and could shut Google out. Owning a free mobile OS guaranteed Google’s services a permanent seat on every phone that ran it.
Early Android, built on the Linux kernel, targeted a keyboard-and-trackball phone resembling a BlackBerry. Then, in January 2007, Steve Jobs unveiled the iPhone. Its multitouch, full-screen design made Android’s prototype look instantly obsolete, and the team rebuilt around a touchscreen.
The Open Handset Alliance
On November 5, 2007, Google announced Android alongside the Open Handset Alliance — a consortium (34 companies at launch) of handset makers, chip vendors, and carriers committed to an open mobile platform. The core code was released as the Android Open Source Project (AOSP) under a permissive license, free for anyone to use and modify.
The first commercial Android phone, the HTC Dream (T-Mobile G1), shipped on October 22, 2008. The strategy was the inverse of Apple’s: where Apple built one tightly integrated phone, Google gave its OS away to every manufacturer — Samsung, HTC, Motorola, LG, and eventually hundreds more. The same dynamic that let Windows-compatible PCs swamp the Macintosh played out again. By 2014 Android ran on over one billion active devices; today it holds roughly 70–75% of the global smartphone market, with Apple’s iOS taking most of the rest.
Owning the Java Question
Android’s app layer was written in the Java language, and Google reimplemented Java’s class libraries rather than license Sun’s runtime. When Oracle bought Sun in 2010, it sued, claiming Google had infringed copyright by copying the structure of 11,500 lines of Java API declarations. The case ran eleven years. In April 2021 the U.S. Supreme Court ruled 6–2 that Google’s reuse of the APIs was fair use — a landmark decision for software interoperability, holding that reimplementing an API to build something new is transformative (see Java).
⚠️ Dead End: The “Open” OS That Isn’t
Android’s openness is its founding myth and its great sleight of hand. AOSP is genuinely open source — but the Android most people use is not just AOSP. The valuable parts, the Google Mobile Services (Play Store, Maps, Gmail, Search, push notifications), are proprietary and licensed only to manufacturers who sign Google’s terms, agree to anti-fragmentation rules, and bundle Google’s apps. The “open” platform is, in practice, a funnel that locks the world’s phones to Google’s services and advertising.
The proof is in the forks that tried to escape. Amazon’s Fire OS, built from open AOSP without Google’s services, struggled for apps and never threatened the mainstream; Amazon’s Fire Phone (2014) was a costly flop. Community ROMs (CyanogenMod, later LineageOS) keep a genuinely open Android alive but reach a rounding error of users. Nobody has built a viable Android without Google — which is the point. As for the founder: Andy Rubin left Google in 2014, and his attempt to reinvent the phone with the Essential Phone (2017) failed within two years. Android conquered the world; the road not taken — a mobile OS open all the way down — was quietly closed off by the company that gave the open one away. The lesson echoes the mobile revolution as a whole: in platforms, “free and open” is often the most effective way to build a monopoly.
