Internet Explorer (formerly known as Microsoft Internet Explorer and windows Internet Explorer, usually abbreviated as IE or MSIE) is a series of graphical web browsers developed by Microsoft and discontinued in 1995 as part of the Microsoft Windows operating system series. As part of the add-on package plus! For Windows 95. You can download them for free or get them in a service pack, and they are included in Windows 95 and later OEM service versions of windows.

Internet Explorer is one of the most widely used web browsers. In 2002 and 2003, it reached the peak of 95% share. This was after Microsoft won its first browser battle with Netscape, the main browser of the 1990s, using bundled software. Since then, its share of use has declined with the release of Firefox (2004) and Google Chrome (2008) and the growing popularity of Mac OS, Linux, IOS and Android operating systems that do not run Internet Explorer. As of August 2016, Internet Explorer's overall market share is estimated to be between 5.45% and 27.38%, or ranked third according to StatCounter's number, next only to Firefox (even lower to sixth when calculating all platforms, next to Opera (after Safari)) (as we all know, browser's market share is hard to calculate). In the late 1990s, Microsoft invested more than $100 million annually in Internet Explorer. By 1999, more than 1000 people were using it.

It also produced Internet Explorer versions for other operating systems, including Internet Explorer for Mac and Internet Explorer for UNIX (Solaris and HP-UX), Xbox 360 version for Xbox and embedded OEM version for pocket Internet Explorer. Later, it renamed Internet Explorer mobile to Windows Phone and windows CE and previous versions, based on Internet Explorer 7 for Windows Mobile.
