The links to Wikipedia content will be displayed above search results, said Yahoo and the Wikimedia Foundation, the nonprofit group that is parent to Wikipedia, on Thursday. The feature will be added sometime during the next several weeks in the United States and in some European, Asian and Latin American markets, Yahoo said.
In addition, Yahoo will provide hardware and resources to Wikipedia.
"Yahoo Search's support and vast user base will provide critical material aid and global reach for Wikipedia,", co-founder of Wikipedia, said in a statement. "Yahoo has been Wikipedia's longest-standing corporate supporter, and with this dedication of resources we will be able to offer Wikipedia content to a growing worldwide audience, while maintaining full flexibility in our ability to expand relationships and freely distribute our works."
Wales said in a Yahoo blog that Yahoo's donation was "purely charitable," adding that it came with no advertising requirement and "no ownership or control of our work by Yahoo of any kind."
The online encyclopedia is based on wiki technology, which is designed to let multiple people work on a project using a uniform interface. In other words, anyone can add to or edit Wikipedia.
