Microsoft Internet Explorer
Microsoft first bundled IE with Windows in 1995 as part of the package called "Microsoft Plus!". By around 2002, Internet Explorer had become the most used browser in the world, but has since lost ground to Chrome, Firefox, Edge, and Safari.
IE has gone through many releases and currently stands at version 11.0.12, with desktop, mobile, and Xbox Console versions available. Formerly available on Mac and UNIX, Microsoft discontinued those versions in 2003 and 2001 respectively.
