In a move aimed at increasing competition against dominant search engine Google, Microsoft would pay Yahoo millions in order to serve search queries on the number two web portal.

Microsoft, the world’s largest software maker, is seeking more users for its Bing Internet search engine, which has about an eighth of Google Inc.’s market share in the U.S., according to research firm ComScore Inc. Yahoo, which has posted three straight quarters of sales declines, may be able to save at least $500 million by working with Microsoft, Yahoo Chief Executive Officer Carol Bartz said in June.

Google had about 65 percent of the U.S. Web-search market in June, according to Reston, Virginia-based ComScore. Yahoo and Microsoft had 28 percent combined.

Online ad revenue has been declining at Yahoo for months.

Google Chrome OS will come in several different flavors.

The Chrome OS and Android are distinctly different operating systems, she added. Android was designed for small mobile devices as well as TV set-top boxes and netbooks, while the Chrome OS will work in larger devices, from netbooks to desktops.

Google is going after Microsoft right where that company has the most strength. Chrome is said to represent a distinct challenge for MS dominance which has remained virtually unchallenged for decades.

In fact, the losses are enormous.

But here’s the thing: the site by Wang’s estimates continues to lose an enormous amoung of money. He calculates that YouTube in 2009 can generate $240.9 million in revenue, through a combination of home page ads, in-video overlay ads, banner ads, sponsored videos and sponsored links. That would about a 20% increase from the $200 million in revenues he estimates YouTube generated in 2008. But he also estimates that the costs of running the site – bandwidth, content acquisition and licensing and other costs – this year will be about $711.3 million. Ergo, he estimates the site this year will lose a whopping $470.6 million.

Considering the current business climate, it’s questionable whether Google would be willing to lay out a significant amount of money for Twitter, despite the potential for the service.

“This feature can’t pull back an email that’s already gone; it just holds your message for five seconds so you have the chance to hit the panic button,” wrote Michael Leggett in the Gmail blog.

“And don’t worry: if you close Gmail or your browser crashes in those few seconds, we’ll still send your message.”

You’ll need to activate the feature first. Under your settings click on the “Undo Send” feature and you’ll see a new button the next time you wish to send email.

“This could be big. Google is seen as disruptive,” said analyst Jon Arnoldo of J Arnold & Associates. “They are a wild card in telecoms and wireless but this is Google and they are very smart at what they do.”

The new features were part of phone firm GrandCentral, which Google purchased. When the search giant took over GrandCentral, analysts weren’t clear in which direction Google would go. Now their grand vision is becoming a bit clearer.

“The core of Google’s business is search and for a long time the industry was concerned about the GrandCentral acquisition. What was the fit? What was the motivation? It will be interesting to see where they ultimately go with this,” Arnold stated.

Users are bound to like the new features, such as unified voice mail. All of the customer’s disparate phone services can now be combined into one. Mobile, and home, and IP phones could share one number, making Google Voice even easier to manage.

Google Voice will allow for free domestic phone calls and will charge for international calls beginning at the rate of 2 cents per minute, which will be charged to a Google Checkout account.

This new offering is bad news for EBay, the owner of the Skype service. Google Voice offers much of what Skype does, but goes a step further.

All messages that come into Google Voice can be translated into text, allowing for easier search and sorting. For people who need a copy of their voicemails, this could represent a giant step forward.

Not only are professionally produced videos by Warner Music at risk, but any video with a Warner Music copyrighted song on it will soon be yanked by YouTube. All told, at least several hundred thousand videos will soon be removed.

The position of Warner Music seems clear enough, they’re not getting paid the money they feel they deserve for such a vast video collection

“We simply cannot accept terms that fail to appropriately and fairly compensate recording artists, songwriters, labels and publishers for the value they provide.”

YouTube and Warner Music had a relationship before search engine giant Google bought YouTube in 2006. Warner was one of the first companies to sign a legit contract with the service. Now their relationship with Google has soured.
