One-click hosting generally describes web services that allows internet users to easily upload one or more files from their hard drives onto the one-click host's server free of charge. Most such services simply return a URL which can be given to other people, who can then fetch the file later on. As of 2005 these sites have drastically increased in popularity, and subsequently, many of the smaller, less efficient sites have failed. Many internet forums exist in order to share such links; this type of file sharing has, to a degree, taken over from P2P filesharing services.
