The IAB released its Internet Advertising Revenue Report yesterday, which details full-year 2011 results and was conducted by PricewaterhouseCoopers. As it has for the last ten years, except for a slight dip in 2009, annual revenue easily beat the previous year—hitting $31.7 billion in 2011, a 22 percent increase over 2010 and an all-time high.

In the last decade, revenues have shot up $25.7 billion at 20.3 percent CAGR. Even so, mobile got recognition as a format that came into its own in 2011, jumping 149 percent to $1.6 billion for the year. 2011 also marked the first year in the report that mobile was broken out as a standalone format. Its revenue increase drove 3.7 percent of the overall 22 percent advertising growth for the year.

While mobile’s 5 percent slice of the full-year digital advertising pie is a tiny one, it’s passed email (1 percent), sponsorship (4 percent) and rich media (4 percent) in share of revenues. Mobile is now tied with lead generation.

It’s likely been singled out due to its big jump over 2010’s $641 million, by far the fastest growing segment. Plus, the platform has traditionally been bemoaned as one that’s not been capitalized on nearly enough.

Nevertheless, digital video (6 percent)  and classifieds (8 percent) are still slightly ahead, as are display and banner advertising which command the highest share of revenues at 22 percent and 47 percent respectively.
