Internet Explorer has been designed to view a broad range of web pages and provide certain features within the operating system, including Microsoft Update.
Microsoft submitted several other features of IE for consideration by the W3C for standardization.
These include the 'behaviour' CSS property, which connects the HTML elements with JScript behaviours (known as HTML Components, HTC); HTML TIME profile, which adds timing and media synchronization support to HTML documents (similar to the W3C XHTML SMIL), and the VML vector graphics file format.
However, all were rejected, at least in their original forms; VML was subsequently combined with PGML (proposed by Adobe and Sun), resulting in the W3C-approved SVG format, one of the few vector image formats being used on the web, which IE did not support until version 9.
On March 17, 2015, Microsoft announced that Microsoft Edge would replace Internet Explorer as the default browser on its Windows 10 devices (while support for older Windows has since been announced, as of 2019 The browser has been scrutinized throughout its development for use of third-party technology (such as the source code of Spyglass Mosaic, used without royalty in early versions) and security and privacy vulnerabilities, and the United States and the European Union have alleged that integration of Internet Explorer with Windows has been to the detriment of fair browser competition.
Internet Explorer 1.5 was released several months later for Windows NT and added support for basic table rendering.
This has resulted in a number of web pages that appear broken in standards-compliant web browsers and has introduced the need for a "quirks mode" to allow for rendering improper elements meant for Internet Explorer in these other browsers.
