comScore’s February Search Query results have Google increasing it share from 67.0% in January to 67.5% in February. Microsoft edged up from 16.5% to 16.7% while Yahoo! decreased from 12.1% to 11.6%.

A Senate committee approved a measure Thursday that would require law enforcement agencies to obtain a court-approved search warrant before reviewing any e-mail or other electronic content. The measure would close what privacy advocates describe as a loophole in the law in which Internet service providers such as Yahoo and Google may turn over e-mail older than six months if authorities obtain a subpoena, which does not require a judge’s approval.

Yahoo named Henrique de Castro, a Google ad executive, as its new chief operating officer, deepening Chief Executive Marissa Mayer's stamp on the company.

Facebook and Internet portals such as Google and Yahoo increasingly provide Americans their gateway for news, but the bulk of voters who catch up on current events daily turn to traditional sources, particularly local television stations, according to a nationwide poll.

Marissa Mayer's move from Google exec to Yahoo! CEO made her one of the most powerful women in the tech industry. Her announcement just three hours later that she's expecting her first child made her "the most powerful pregnant woman in America," says Lisa Belkin of The Huffington Post.

Yahoo is hiring longtime Google executive Marissa Mayer to be its next CEO, the fifth in five years as the company struggles to rebound from financial malaise and internal turmoil. Mayer, who starts at Yahoo Inc. on Tuesday, was one of Google's earliest employees and was most recently responsible for its mapping, local and location services. Mayer, 37, began her career at Google in 1999 after getting her master's degree at Stanford, the school Google's co-founders attended.

Google is considering participating in a bid for troubled Internet search pioneer Yahoo!, according to a published media report. Google has held talks with at least two private-equity firms about helping them to finance a purchase of Yahoo!'s core business, according to the report, published Saturday on The Wall Street Journal's Web site.

Slowly but steadily, Microsoft Bing has become a potent threat to Google in the search market. Over the last few months, Microsoft’s aggressive strategy with Bing has started to yield market share gains over competitors Google, Yahoo and AOL in the U.S. search market. Bing’s market share, which was around 11% in September 2010, is now close to 14% as of February 2011.

No wonder Google seems so panicked about Bing. The latest results from market researcher Experian Hitwise show not only that Bing grew at Google's expense in January. They also show that Bing is delivering more accurate results. In the U.S., Bing now powers more than 27% of search results, up from 25% in December. That's despite a slight decline in traffic to Yahoo's search site, which has been powered by Bing since December.

Yahoo Inc's quarterly net revenue slid 4 percent and it forecast a further slide this quarter as it struggles to revive growth in the face of intense competition from Google and Facebook.
