Microsoft released Internet Explorer 1.0 in its Windows 95 Plus Pack. Internet Explorer was built upon software licensed from Spyglass, an offshoot of NCSA that owned the technology behind the Mosaic browser. Microsoft bundled Internet Explorer into its operating system and provided it free of charge. Microsoft's approach was smart; two years later Microsoft had replaced Netscape as the leading browser provider, with 49 percent of the market compared with 46 percent for Netscape, according to Janco Associates.
