Microsoft has announced that it will release the first public beta version of its Internet Explorer 9 (IE9) web browser on 15 September.
Tech news site PC World has reported that the Redmond-based software giant has sent out invitations to selected software developers, web designers and members of media sector to attend the launch of IE9 at the Concourse Exhibition Centre in San Francisco, California.
Invitations for the event, named “Beauty of the Web” have been sent out in form of a riddle.
