Internet Explorer, abbreviated IE or MSIE, is a proprietary graphical web browser made by Microsoft and included as part of the Microsoft Windows line of operating systems. It has been the most widely-used web browser since 1999.
Internet Explorer has been designed to view the broadest range of web pages and to provide certain features within the operating system, including Windows Update. During the heydays of the historic browser wars, Internet Explorer superseded Netscape by supporting many of the progressive features of the time.
The Component Object Model (COM) technology is used extensively in Internet Explorer. It allows third parties to add functionalities via Browser Helper Objects (BHO); and allows websites to offer rich content via ActiveX.
