Dogpile

Dogpile is a metasearch engine for information on the World Wide Web that fetches results from Google, Yahoo!, Yandex, Bing, and other popular search engines, including those from audio and video content providers such as Yahoo!. History Dogpile began operation in November 1996. The site was created and developed by Aaron Flin, who was frustrated with the varying results of existing indexes and intending on making Dogpile query multiple indexes for the best search results. It originally provided web searches from Yahoo! (directory), Lycos (inc. A2Z directory), Excite (inc. Excite Guide directory), WebCrawler, Infoseek, AltaVista, HotBot, WhatUseek (directory), and World Wide Web Worm. It naturally drew comparisons with MetaCrawler, a multi-threaded search engine that had existed before, but Dogpile was more advanced, and it could also search Usenet (from sources including DejaNews) and FTP (via Filez and other indexes). In August 1999, Dogpile was acquired by Go2net, who were already operating MetaCrawler. Go2net was then acquired by InfoSpace in July 2000 for $4 billion. Dogpile received a design facelift for the first time in December 2000. The Dogpile search engine earned the J.D. Power and Associates award for best Residential Online Search Engine Service in both 2006 and 2007.
