The history of Android is a fascinating journey of innovation, collaboration, and evolution that spans several decades. The story dates back to 2003, well before “smartphones” became pervasive, when Andy Rubin, Nick Sears, Rich Miner, and Chris White co-founded a start-up “Android Inc.” in Palo Alto, California. However, the company was later faced with financial challenges which brought Google into the picture. Google recognized the product’s potential and sealed a deal worth $50 Million to acquire Android in 2005.

Silicon Valley-based designer Irina Blok created the iconic Android logo while working for Google. The logo, resembling a blend of a robot and an insect, was designed to be open and welcoming, reflecting Android's open-source nature. Over the years, the logo has been subtly refined to stay current with design trends. In 2019, Google introduced a modernized version with a new typeface for "Android" and a slightly tweaked robot design, maintaining its iconic look with a refined touch.

Beginning with Android 1.5 "Cupcake," Android versions were named after desserts as part of a marketing strategy to add a fun and memorable touch to each release. However, with the introduction of Android 10, Google transitioned to a numerical naming system recognizing that some dessert names were not well-known or easy to pronounce in different cultures. This change makes Android version names universally understood and appreciated.

Since its initial release, Android has undergone numerous updates, each adding new features and improvements. The first commercial version, Android 1.0 codenamed "Astro Boy," was released in September 2008 on the HTC Dream (T-Mobile G1 in the US), making it the first-ever Android device.
