Stuck at an airport? Have an internet ready device? Don’t want to pay for wifi? No problem!

The leading internet search powerhouse is planning to offer free wifi in 47 of the nation’s airports. Seems to good to be true? Think again. This is Google’s holiday present to the nation.

There is a positive side to this as well. They are running a charity to raise funds for 3 non-profit organizations: Engineers without Borders, One Economy Corporation and Climate Savers Computing Initiative. When Google WiFi users first log on, the landing page will offer them the option of donating to the organizations. Google will match donations of up to $250,000 per airport.

This awesome deal won’t last forever though. The final day is January 15, 2010, when the holiday season ends.

Google Inc is acquiring mobile advertising company AdMob for $750 million, furthering the company’s push into the fast-growing market of Web-enabled cell phones.

The all-stock deal gives Google, whose Android software is increasingly used to power smartphones such as the Motorola Inc Droid, an important element to monetize mobile Internet traffic.

“Mobile advertising has enormous potential as a marketing medium and while this industry is still in the early stages of development, AdMob has already made exceptional progress in a very short time,” said Google VP of Product Management Susan Wojcicki.

Last month, Google said its mobile searches increased 30 percent quarter-over-quarter in the third quarter.

Google CEO Eric Schmidt also said last month that the company was interested in resuming its acquisition efforts, after taking a breather during worst of the economic downturn. Schmidt said Google would acquire on average one company a month.

Google said the deal has been approved by both Google and AdMob and is subject to customary closing conditions.

You thought Google already had everything? Think again.
