INTRODUCTION :INTRODUCTION :

The Smartphone operating system Symbian OS isproduced by the software development andlicensing company Symbian Ltd.

Symbian Ltd was established in June 1998 and isheadquartered in Southwark in the UK, and thecurrent CEO is Nigel Clifford.

In 2008, the former Symbian Software Limitedwas acquired by Nokia and a new independentnon-profit organization called the SymbianFoundation was established
