Internet Explorer is Microsoft’s native browser, the first iteration of which was released in August 1995 as The Internet Jumpstart Kit for Microsoft Plus! with Windows 95. Updates and new versions of Internet Explorer came in rapid succession, with IE 2 coming out later in 1995 and others following quickly, so that by 2001 six versions of Internet Explorer had been released. Internet Explorer became popular almost immediately and remained a popular browser; within one week of the release of Internet Explorer 3 in 1996, one million copies had been downloaded. New versions continue to be released, and Internet Explorer continues to be among the most popular web browsers.
