Search Engine Size War I:
December 1997-June 1999
When AltaVista appeared in December 1995, it used an index much larger than any of the other search engines at that time. Thus, competition forced others to increase their sizes in early 1996. After these initial moves, sizes stayed about the same through September 1997. But by the end of that year, AltaVista and Inktomi began the first of the serious Search Engine Size Wars, competing to claim the bragging rights of being biggest. Inktomi failed to keep up, but Northern Light jumped in to compete with AltaVista in pursuit of the 150 million page mark.

Search Engine Size War II:
September 1999-June 2000
Just when AltaVista and Northern Light were celebrating hitting the 150 million document mark, newcomer AllTheWeb appeared with a record-setting index size of 200 million documents. Suddenly, a new round of size escalation began. The title of biggest flip-flopped between AllTheWeb and AltaVista at first. However, Google put a decisive stop to the war in June 2000, when it set a new benchmark of 500 million pages indexed and started growing well past its challengers.

Search Engine Size War III:
June 2002-December 2002
After a long period of being the size king, AllTheWeb grabbed the title back from Google by declaring it had broken the 2 billion document mark. Soon after, Google grew the number of documents it reported indexing up to the 3 billion page mark. Inktomi also released a new version of its search engine that claimed this index level.
