Crikey! Eh? Microsoft-Yahoo Deal Cleared in Australia and Canada.

They’re grinning like a shot fox up at Microsoft today now that the company’s advertising partnership with Yahoo has been cleared by antitrust regulators in Australia and Canada.

“Microsoft and Yahoo!’s share of online paid search advertising queries in Australia was limited,” the Australian Competition & Consumer Commission said in its notice of approval. “In combining search engine platforms, Microsoft and Yahoo! may have been able to achieve the necessary scale to provide effective and sustainable competition to Google, which had a very large share of online paid search advertising queries.”

Great news for the two companies, whose plan to consolidate two of the search market’s three largest players is currently under review by antitrust regulators at the U.S. Justice Department. Should it be approved, Microsoft (MSFT) and Yahoo (YHOO) will together control nearly 30 percent of the U.S. search market, giving them a better chance to compete with Google (GOOG), which holds a roughly 65 percent market share.

“We continue to believe that this deal will create a true, competitive alternative in the marketplace that will benefit consumers, advertisers and publishers,” the companies said in a joint statement. “We remain hopeful that the agreement will close in early 2010.”
