== 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).
