History of Favicon

In March 1999, Microsoft released Internet Explorer 5, which supported favicons for the first time.

Originally, the favicon was a file called favicon.ico placed in the root directory (e.g., of a web site. It was used in Internet Explorer’s favorites and next to the URL in the address bar if the page was bookmarked. A side effect was that the number of visitors who have bookmarked the page could be estimated by the requests of the favicon. This side effect no longer works, as all modern browsers load the favicon file to display in their web address bar, regardless of whether the site is bookmarked. – Wikipedia has 142 favicons collected for the Worldwide Favicon Collection.
