This is just the beginning — Google Chrome is far from done. We’re releasing this beta for Windows to start the broader discussion and hear from you as quickly as possible. We’re hard at work building versions for Mac and Linux too, and will continue to make it even faster and more robust.

I’m no expert in this but I do believe there’s a big reason for Google to launch their own browser (Google Chrome). Now let’s read some facts on why they build it:

1. A fresh take on the browser
At Google, we spend much of our time working inside a browser. We search, chat, email and collaborate in a browser. And like all of you, in our spare time, we shop, bank, read news and keep in touch with friends – all using a browser. People are spending an increasing amount of time online, and they’re doing things never imagined when the web first appeared about 15 years ago.

2. Since we spend so much time online, we began seriously thinking about what kind of browser could exist if you started from scratch and built on the best elements out there. We realized that the web had evolved from mainly simple text pages to rich, interactive applications and that we needed to completely rethink the browser. What we really needed was not just a browser, but also a modern platform for web pages and applications, and that’s what we set out to build.

Actually, I don’t think that will be the best reasons for them to build it. From my own observation, there’s something that more reasonable for them to launch it. For those who already forgot about their split profit with “default search engine”, let me share with you some info about it:

1. Mozilla reported revenue of $66.8 million, up more than 25 percent from last year. According to Mozilla, 85 percent of that revenue came from its partnership with Google, who serves ads alongside the search results generated by the Firefox browser. Source: Mashable.com – 2007.

2. Google To Pay Mozilla $0.5 Billion To Retain “Default Search Engine” Place.
- Google, Yahoo and MS have all put in bids trying to secure the place of “default search engine” on Mozillas firefox browser, But Google are believed to have put in an exceptionally large bid of 500 million dollars that would would also make Google the default search engine on all Mozilla software which has an internet search function.

There you go!
Now do you think Google will pay all those “default search engines” million of dollars again in the future? Maybe yes but the significant is they don’t need to pay so much as they are paying right now. Money .. money … money…
