Safari is a web browser developed by Apple Inc. and included in Mac OS X. It was first released as a public beta on January 7, 2003, and was included as the default browser in Mac OS X v10.3. A beta version for Microsoft Windows was released for the first time on June 11, 2007 with support for Windows XP and Windows Vista. Safari has also been run unofficially on Linux under Wine, but the GUI and graphics do not render properly.
Originally the browsers layout drew many comparisons to Firefox, though lacking Firefox's modularity. As of Safari 4 however, the developers have gone for a more Google Chrome like appearance. Safari includes a built-in RSS reader, native Quicktime support, an integrated pop-up ad blocker and a Web Inspector - a DOM Inspector-like utility that lets users and developers browse the Document Object Model of a web page.
As of January 2009 the market share held by Safari is a respectable 8.29%.
