Microsoft's Bing has seen slow but steady month over month growth since it launched this past summer. However, September saw Bing's share of the U.S. search market fall to 8.5 percent.
New numbers from StatCounter show that rather than continuing its trend of acquiring more market share at the expense of competitors Google and Yahoo!, Bing fell by 1.1 percent (bringing the decision making engine down from 9.64 percent to 8.51 percent) while Google rose two full percentage points, moving to 80.08 percent, up from the 77.83 percent it had in August. Yahoo! also declined, moving to 9.40 percent from 10.50 percent.
This is rough news in itself, however the fact that its Bing's first decline since it launched in May.
"The trend has been downwards for Bing since mid August," commented Aodhan Cullen, CEO, StatCounter. "The wheels haven't fallen off but the underlying trend must be a little worrying for Microsoft."

Bing Cuts Itself a 10% Slice of the Search Pie
I don't suppose you didn't read anything previously about Bing. If you notice, the release of Bing in July meant an increase in search, which most definitely was reported. Bing sat mostly stagnant in August (did you want an article about that?) but then lost all that Bing momentum in September. You want the article titled "Bing increases Microsoft's share of internet search", not "Bing increases infinity percent of search over previously non-existent Bing".
That said, same happened with Chrome (the browser). It got a big jump, then people stopped caring and went back to what they always used. Same with Bing, it had a lot of hype, some commercials, and now no one cares. I think search companies seriously underestimate the individuals ability to find what they want on the internet. I don't need every site that matches my query, just one thats good enough). "Decision engines" like bing are nice, but not necessary for everyday use.

i suppose you use Linux so Microsoft stays in check and Windows is not an obscene monopoly
In all honestly I used the thing twice or so and it was awful, Google ftw.
However, most of them had brains in their heads, and preferred Google's fast loading, accurate, low on ads searchengine over Bings.
In other words, now that nearly the whole world knows Google rocks, only the Bing fans and geeks stay with MS' solution of inaccurate links, spam, ads, and amounts of unnecessary data.
Its just a search box with the company logo above it... Generally thats all I need, or want when I'm doing a search, all the other garbage doesn't matter.
The lack of clutter also makes for easier mobile browsing, There's nothing to load with google, no images, or animations, just the browser. I'd wager that the popularity of smart phones has pushed Google's percentages up simply because its easy on low bandwidth connections.
they wil have to tweak it some more or bye bye bing
So go ahead, Support the clandestine facets of the US government, use Google.
So go ahead, Support the clandestine facets of the US government, use Google. Ever wonder why a search engine company wants to hold everyones medical information and even your DNA sequence?
