Internet advertising revenue, fueled by increases in classified ads, lead generation and display advertising, grew by 35 percent last year to $16.9 billion.

In the fourth quarter alone, $4.8 billion was spent on online advertising, a 33 percent increase over the same quarter a year earlier and the most for any quarter, according to a report by the Interactive Advertising Bureau.

The jump in revenue caps a 10-year span in which the Internet sector has gone from $907 million, or less than 1 percent of all advertising, to 5.9 percent of the $286 billion spent last year by advertisers.
