Yahoo! completed 10 years on 3rd March.
Yahoo!, which started off as a search-engine has now diversified into many areas, so that it is not perceived any more as specialising in any single vertical. Meanwhile Google has beaten Yahoo! as the top search engine.
Yahoo! is remarkable in that it has survived the dotcom bubble and the meltdown of the Internet during early 2000. When many search engines and web startups such as Altavista, Excite, Lycos, Go.com, Snap etc fell down by the wayside, Yahoo! is still going strong with a 50 billion $ market cap.
Google has been the leader in taking new technologies to the market, with Yahoo! being forced to follow-up. The new Yahoo! search has borrowed a lot of concepts from the Google, not just the look n feel. Google has been the pioneer in broadening the search market from simple keyword/directory search to specific search verticals such as newsgroup search, image search, catalog search, product search, scholar search, news search, video search etc.
However Yahoo! has improved their search tremendously since they parted ways with Google last year. Though forced to do catch-up, Yahoo! seems to be doing a good job of it now a days, with Microsoft tagging along.
So who will win the search war ultimately? One yer back I would have confidently said "Google" (Yahoo! who?) but not anymore. The field is wide open once more.
