Early Beginnings
Android was first conceptualized by Andy Rubin, Nick Sears, Rich Miner, and Chris White in October 2003. Initially, the project aimed to create an operating system for digital cameras. However, the team soon realized the market for such systems was limited. In 2005, Google acquired Android Inc., and Andy Rubin and his team continued to work on the operating system. Google's acquisition marked a significant turning point for Android, providing the necessary resources and support to transform the project into a full-fledged mobile operating system.
