Flock, a Web browser that was designed for information-sharing as well as surfing, is being discontinued after its development team was bought up by Zynga Inc., the maker of "FarmVille" and other online games.
A notice on the Flock website says support for the browser will end on April 26. It's no longer available for download. The site warns that because security updates will no longer go out, users should switch to another browser.
Zynga bought the Flock team in January, but not the browser itself or the Flock.com website.
The first public beta version of Flock launched in 2006. It was initially based on the technology behind Firefox and added features to make it easier to blog and share bookmarks and photos. Later versions were based on Google's Chrome and added integration with Facebook and other social networks.
Last year saw the launch of another "social" browser, called RockMelt. Behind it is Marc Andreessen, the creator of the first commercial Web browser, Netscape.
