I'm quite a fan of google and we all know how google innovates by releasing one brilliant product after the other. Why is it that google has to innovate?

In fact innovation is the only way to survive for google. Tell me, how long does it take you to stop using google and switch to another search engine? Less than ten seconds?

But it is quiet hard to switch from a microsoft product to an alternate product as it runs on your hardware and there are so many things involved in switching. So google has to keep you there. Build its brand value because most part of google's revenue comes from that 50 cents or so they make when you click on those ads which gets displayed along with the search results. So google gives you one product after the other. gmail, picasa, orkut, blogger, google docs and what not. Unlike microsoft's products, google's products run on the web and does not run on hardware. And almost all services are free and some of them can substitute microsoft products. So as more people use the products, google spreads its tentacles even more.
