"In 1996, the iframe tag was introduced by Internet Explorer; like the object element, it can load or fetch content asynchronously. In 1998, the Microsoft Outlook Web Access team developed the concept behind the XMLHttpRequest scripting object.[4] It appeared as XMLHTTP in the second version of the MSXML library,[4][5] which shipped with Internet Explorer 5.0 in March 1999.[6]"
This was Microsoft's single biggest contribution to the early web. Everyone likes to hate on IE but actually it did include a lot of innovation.
