A DigitalPoint Forums thread refers to last week's Hitwise Press Release that states that Google has received 64% of US searches for the month of August. Danny Sullivan also reported with these findings at Search Engine Land and followed with another article reporting the Neilsen NetRatings for August 2007. Clearly, Google is on the top of the popularity statistics for the US.
Forum members believe that the smallest players in the Top 4 should close up shop. Given that there are hundreds of other search engines outside the top 4, I'm not so sure I'd agree. Plus, as other members add, competition should exist.
Other search engines are innovative in their own space. For example, a forum member believes Ask is making an impact with its advertising strategy:
ASK.com has been making a big push at google using Radio and Tv ads recently in the USA specifically detailing about the search results with video, ipod and other major sectors that bring it "above" googles.
In general, though, Google might be big in some countries, but in Asia, for example, they're not necessarily leading in search popularity.
