1999 March

Favicon (a combination of the words favorite and icon) first appeared in Internet Explorer 5.0. The term favicon refers to a webpage icon that appeared in older browsers in the address bar next to the URL or in favorites. Originally, favicon had to be placed in the root directory of the website under the name favicon.ico, and its dimensions were typically 16×16 px or 32×32 px. In December 1999, favicon was standardized by W3C in the recommendation for HTML 4.01.
