AltaVista
before Google, it was the most popular Search Engine, at least among the active-online crowd.
created by DEC; Com Paq bought DEC in 1998
in 1996 became the Search Engine behind Yahoo's raw-search results (vs it's in-house category-search engine)
in 2003 was bought by Overture, which led to it becoming part of Yahoo. By early 2004 it was gone completely
