No, as long as Google keeps providing good quality search engine results, it won't be replaced by BING. I tried using BING once, and all the results that I got were not accurate and a waste of time. For searching, I'd rather use Google (maybe Yahoo) than Bing.
Traffic isn't everything, and Facebook is a terribly-run company. So they have a lot of traffic... what have they done with it? -They've made a number of VERY unpopular interface changes which require more clicks to do even the simplest things. -They've dropped the ball on even the most basic security measures, such as hiding one's email addresses. -They've made everybody's profile public by default. -They've made the chat feature a complete wreck. I have yet to see a chat feature that's more unreliable. Just more trouble than it's worth... -They haven't managed to implement a successful advertising/monetization system -- despite the fact that, as CEO Mark Zuckerberg stated, he owns all the stuff you upload and can sell it to third parties. Privacy...? What privacy? The bottom line is that the developers and programmers who work at Facebook are not the sharpest tools in the shed, and that Facebook's traffic is not because it is a well-run or promising company. If anything, I'd bet that Facebook fails way before Google. (Myspace and Friendster got a lot of traffic back in the day, too, and Facebook is in no way different...)
I dont think Google will ever be replaced or even lose a very large part of their customer base. Even on TV shows you the 'Google It" constantly. It is the norm and will be for at least the forseeable future.
How to use the traffic is a different set of 20 dollar bills. Those networks didn't do anything significant with their traffic that I know of. Of course Facebook will be history at some point if they don't expand into other areas. It will be the same boring crap and will be replaced by the next geeky 12 year old with an html site. That's why Google keeps invading other turfs, to stay alive and get traffic. Mark seems to be very ambitious and has given hints of getting into search at some point. Now, if you put 2 and 2 together from the latest happenings at FB, you'd know something is cooking there.
Search isn't an easy field to get into; for Facebook to make an effort at introducing an internet-wide search functionality will take a whole lot more than just traffic. When you take privacy concerns, the complete inability of Facebook programmers to successfully implement even the simplest features (such as chat), and the already extremely underwhelming performance of Facebook's current advertising system into account... There's pretty much no way I can see it working. How on Earth would they be able to do it well and turn a profit? It would take a lot more than luck, traffic and ambition... People hang out on Facebook for the same reasons they used Myspace and Friendster -- and Facebook doesn't seem do be doing much more with the traffic it gets than the aforementioned two.
Google has become a household name but that doesn't mean they can slack off and still stay on top. Search is a very competitive market so to stay on Google will have to keep proving that they are the best search engine.
Everything gets replaced eventually. GM was once too big to fail, as was the USA. But hire the wrong CEO or president and look at what can happen. All it will take for Google or any other large cyber property to fail is a shift in attitude.
Microsoft has poured how many millions of dollars into their marketing of Bing, and they barely got a few percentage points. I do not see it happening.
No, Google is the top of the search engine and mostly traffic is coming from the Google, more than 80% of the traffic is coming from the Google so by with this great amount, it is totally impossible to replace the Google with any other search engine...
There is a reason why Google is called the Big "G." It is because Google takes over the whole World Wide Web. Bing is nothing but a small competition.
When Bing took over Yahoo search, market share for Yahoo dropped from 20+% to under 10% while Bing dropped to 3%. Google rose. What does that tell you about Bing?
