The new figures released on Wednesday by the Interactive Advertising Bureau and PwC also reported record online ad revenue increases in the fourth quarter of 2010, up 19 percent to $7.5 billion.
“We now have had five consecutive quarters of growth since the great recession impacted interactive advertising in 2009,” Sherrill Mane, senior vice president, industry services at the IAB, said in a statement.
The report found that the most popular form of advertising was search, which represented 46 percent of revenue and increased 12 percent from 2009.
Digital video advertising accounted for 5 percent of total ad dollars spent online in 2010, or $1.4 billion.
Display advertising, which also includes video, jumped 24 percent to almost $10 billion last year.
The fastest growing form of advertising in 2010 was sponsorships, which soared 88 percent to $718 million.
“More time spent online, especially with increases in digital video and social media, has certainly helped to fuel the continued growth,” David Silverman, PwC assurance partner, said in a statement.
