Are Any Google Competitors like Bing, etc In Anyway competitive?

Are Any Google Competitors like Bing, etc In Anyway competitive? I have a question that based half from business needs and half from just plain curiousity. Obviously the search engine game has on massively dominant player, Google, The Big G or G who must not be named to list of a few of its lesser known monickers. Obviously I dont need to tell anyone here how dominant it is, but it seems crazy that to a newbie like me to the internet marketing scene, I cant list off more than three competitors. Bing is one for sure, Ive had Bing strong armed into the position of my default search engine by way of an inconspicuous ticked box during many a download more times than I care to mention, and given that it is relatively well know I have to assume that it is somewhat of a relevant player. Yahoo is obviously another player, but from my uneducated position it seems that this search engine is becoming less and less relevant as the years go on. And thats it. I cant name another single search engine, and from the point of view of someone who just until recently, used the internet for purely just consumption purposes, that says a lot. So my question is. Are there any more competitors? I know many east asian countries have their own version of google etc but I mean in the main western markets? And also are the current main competitors, Bing and Yahoo in any way relevant these days? From a perspective of someone trying to market my own business, are they worth the time in terms of the possibilities of driving a small amount of traffic to my site through them? Thanks as always.
