Yahoo has twice the market share of bing. Bing and yahoo combined would have less than hall the market share of Google.
I think also some #s for both BING and Y! are overplayed due to "forced" searched (go roll over keyword on Y news and you'll get a searched box popup). It's likely Google controls over 75% of the search market (in some areas up to 85%+) while Bing/Y! only hold around 20-25% MAX for both.
yahoo is ok ,but it is not free for all over the world. so compared to google , google captured all the market, but in the future who will be the first one , it is still unknown!
Google still has a stranglehold on the market. Google has way more traffic than Yahoo and Bing combined. I wouldn't even pay much attention to the merger.
Bing and Yahoo combined make up less than 23% while Google, by itself, is at least 65% of the market but that's the wrong way to look at it. Yahoo is not Bing! Yahoo is only using their search engine. They are not merging into one entity.
