Ad money begins to trickle in for bloggers

It is no longer unusual for blogs with just a couple thousand daily readers to earn nearly as many dollars a month. Helping fill the pockets of such bloggers are programs like Google's AdSense and many others that let individuals - not just major publications - tap into the rapidly growing pot of advertising dollars with a click of the mouse.

In 2006, advertisers spent $16.9 billion online, up steadily each year from $6 billion in 2002, according to the Internet Advertising Bureau. In the first half of 2007, online advertising reached nearly $10 billion, a nearly 27 percent increase over the first half of 2006.
