Wikipedia
Veropedia was a free, advertising-supported Internet encyclopedia project launched in late October 2007. It was taken down in January 2009 pending creation of a new version, which never arrived.
Veropedia editors chose Wikipedia articles that met the site's reliability standards; information was then scraped, or chosen by an automatic process, and thereafter a stable version of the article was posted on Veropedia.
Any improvements required for articles to reach a standard suitable for Veropedia had to be done on Wikipedia itself. This model was intended to provide benefits to both projects: Wikipedia's open nature and large volume, and Veropedia's stability and perpetuity.
the site, still in beta, had checked and imported more than 5,800 articles from the English Wikipedia into its public database. Although Veropedia intended to eventually support itself completely through advertising, the project was mainly financed by those involved in the project, and in January 2009 it disabled articles and advertisements and announced a coming "Beta2". The "Beta2" never arrived and the articles were not restored.
