Bing, Microsoft's attempt to take on Google directly. When it first launched there was quite a bit of fanfare and its market share grew quickly. It didn't exactly hack away at Mountain View's dominance, but it certainly made a small dent. Since then, things have slowed down and other players have asserted themselves in the global search battlefield. While Baidu has been riding high for quite some time, Yandex is a relative new-comer to the leader board. And, somewhat surprisingly, has already surpassed Microsoft for global market share according to stats provided to us by comScore. Though the margin is small, the Russian company saw more searches performed through its site than Microsoft in both November and December of 2012. The difference is small enough that those positions could swap again but, where as Bing has seen its numbers plateau over the last six months, Yandex has continued to grow. Of course, neither is anywhere near challenging Google which accounts for roughly 65 percent of the search traffic according to comScore's numbers and both only see about half the traffic of the number three competitor, Yahoo. Microsoft can still claim one victory over Yandex in the number of unique searchers, though. If you're curious for more we've put the entire chart after the break.
