Google Voice is said to be a competitive threat to voice services that already come with the iPhone. Industry analysts have also said that AT&T is likely concerned that its company could lose revenue as a result of Google Voice services.

The FCC is looking into the matter as part of its continuing investigation regarding wireless open access and handset exclusivity. The letters also seek to find out if AT&T had any input in the decision to reject Google Voice.

Ironically, Google CEO Eric Schmidt announced his resignation from Apple’s board Monday, August 3. Although his resignation came just days after the FCC’s investigation began, the FTC had already been investigating ties between the companies and whether they were breaking antitrust laws.

What will become of the FCC’s investigation? How will it impact Apple’s iPhone? Was the timing of Eric Schmidt’s resignation simply a coincidence? Will these proceedings affect Google and Apple’s cordial relationship?

In summary, Microsoft will power Yahoo Search and Yahoo will become the exclusive search advertising provider for Microsoft’s search engine, Bing. Microsoft’s AdCenter will operate self-service advertising for both companies, but each company will maintain its own separate display advertising business and sales force.

In an interview with WebProNews, search industry leader Danny Sullivan summed up his thoughts by saying what the deal meant for each company. He said, “[A] big win for Microsoft, a lot of questions for Yahoo.”

The deal will likely face a close antitrust review from regulators especially regarding Steve Ballmer‘s claim that the partnership would provide a stronger competitor for Google.

It is still early, but nonetheless, there are many unanswered questions associated with the deal. Could Yahoo have bargained a better deal? How will Google respond? Is the deal a good move for Yahoo? How will the partnership influence the future of online advertising? What are the impacts on the SEO industry?

Even Danny Sullivan said it was too early to accurately speculate on what may happen, but he did say he didn’t expect any dramatic changes for SEO.

Provided the deal is granted regulatory approval, Yahoo and Microsoft said they hope to have their partnership finalized by early next year.

Google Chrome OS is open source and will initially be intended for netbooks; however, the system is said to be equipped to power large desktop systems as well. The three main aspects of the operating system are speed, simplicity, and security. Although Google will construct its own windowing system, the new OS will run on top of the kernel from the open source Linux OS.

According to the Google blog post making the announcement, the OS will not be available to consumers until the second half of 2010.

As Google prepares to enter the operating system market, many questions come to mind. First of all, is this a direct attack against Microsoft since Bing appears to be making legitimate progress? Will Google’s OS exist as a serious contender to the alternative operating systems? How will consumers and computer manufacturers react? Will Google be hit with more antitrust investigations?

Although there are many unanswered questions associated with this news, one thing that is certain is that Google has just taken on a challenging mission.
