Apache leads the way in web server hosting.‚ In their June 2007 survey, Netcraft estimates that over fifty percent of all web sites run on apache web servers.‚ It was as high as seventy percent in 2006.‚ In other words, the software that powers the majority of the web is not a corporate development, but a product of collaboration and choice.‚ While a core set of code exists for apache, developers and systems engineers can customize the exact implementation of the apache web server.‚ In addition, while a foundation oversees the project, no one really controls the code; code can be added to or taken away.‚ ‚ Apache represents the movement into decentralized leadership.‚ The development of open source software is representative of the change and transformation of leadership.
