December 18, 2013: The Nmap Project is pleased to release our new and improved Icons of the Web project! Since our free and open source Nmap Security Scanner software is all about exploring networks at massive scale, we started by scanning the top million web sites for 2013 (as ranked by the analytics company Alexa). We then downloaded each site's favicon—the small icon displayed next to a site title in browser bookmarks and tabs.
We scaled the icons in proportion to each site's monthly reach (popularity) and placed them in a giant collage. The smallest icons—for sites visited by only 0.00004% of the Internet population each month—are 256 pixels square (16x16). The largest icon (Google) is 394 million pixels. The whole collage is 5 gigapixels.
This is an update to a similar project we performed in 2010. That edition proved very popular. It was written up in the New York Times and other sites, exhibited at the Newseum in Washington D.C., and even found its way into the Guinness Book of World Records (see the press section for more). It is interesting to compare the new data with the old to see how the Internet has evolved in recent years.
