Understanding and knowing the potential external influences when making a business decision is extremely important. It could be changes in government policy or in this case a change in search engines. Over the last few months Bing has been ferociously marketing their new search engine “BING” with great success.  According to comScore, Microsoft has increased it’s share of search each month, while Yahoo has been on a steady decline.  In March 2010 Yahoo’s percentage of search was down .06% since November 2009 while Microsoft’s was up 1.4%.  Both Microsoft and Yahoo combined still are no match for Google’s Goliath numbers at 65.1%.
