Historical perspective: Some of the best hybrid search sites included Hotbot and InfoSpace, here's a look back...

HotBot - An early favorite, a hybrid search engine developed by HotWired and Inktomi in May 1996, and once acquired by Lycos, it exploited NOW (Network Of Workstations) parallel computing technology to achieve scalable, supercomputer-class performance from clusters of reliable, commodity workstations and high-speed local area networks (LANs). Nobody cared if it sounded confusing, the best part was the flashy interface.

InfoSpace - A classic web service founded in March 1996 by Naveen Jain, it pioneered the original vision of delivering real-world information and services anytime, anywhere, and on any device. It used to be an online service that enabled you to locate listings of people, businesses, toll-free numbers, e-mails, addresses, maps, etc., it morphed into an Internet infrastructure service company, and ultimately became just another advertising network.
