According to ComScore, in US last month, Yahoo share of the search market rose by 8% while Google's share decrease by the same. I think this is quite significant, I wonder what it was down to. Hopefully this is not a blip but signs that Yahoo's fortunes are on the up. There is not danger of Yahoo catching up with Google because this only took Google's share of the market from 70% to 62%. Microsoft share of the market remain unchanged.
