Google and Android are synonymous with each other and most of us believe that Google created Android. But actually it is not. Three persons behind the invention of this OS were Andy Rubin, Rich Miner, Nick Sears and Chris White. They have strong ties with T-Mobile. So, it was T-Mobile who introduced the first Android phone to the world.
It was in 2005 that Google acquired Android Inc. Now Android controls over 85% of smartphone OS market.
