History At The  Beginning Of Android :


The history began when a man named Andy Rubin picked android.com as his personal website, and his colleagues used  Android as his nickname at work. That eventually become the name of the company he founded, and the name of the Operating System they developed. 

The name Andrew and the noun Android share the Greek root Andros, which means man.
