Internet Explorer 5.5

Internet Explorer is Microsoft's venture into the Web Browser market. The initial version of Explorer was incarnated from Spyglass Mosaic which Microsoft licensed for a modest quarterly fee and a share of the non-Windows product revenues. As Microsoft decided to distribute Internet Explorer "free of charge" with their Windows operating system, they were able to avoid most royalties. This resulted in a lawsuit and a US$8 million settlement in January 1997. Being included in Windows since Windows 95 and beyond, it quickly overtook Netscape in the first Browser War and retained ~95% of market share until the early 2000's when popular alternative browsers such as Mozilla Firefox came to market sparking the 2nd browser war. Internet Explorer was long known for disobeying set web standards by the W3C until version 9 when Microsoft took a new commitment to HTML5 and web standards.
