Amtrak will offer wireless Internet service on the high-speed trains that ferry passengers along the busy Northeast corridor, in another bid to lure business travelers away from the airline shuttles.

Wi-Fi access will be available starting in March on Acela trains traveling between Boston, New York and Washington, says Amtrak spokesman Cliff Cole. Initially, the service will be free.

Upping the competition with airlines such as Delta and US Airways, which offer short flights to travelers up and down the East Coast, is one reason for the new service, Cole says.

Google handles about two-thirds of all Internet searches. It owns the largest online video site, YouTube, which is more than 10 times as popular as its nearest competitor. And last year, Google sold nearly $22 billion in advertising, more than any other media company in the world.

With all those riches and more, how is Google a relatively small company, one that is vulnerable to competition and whose luck could turn any day?
