U.S. digital advertising revenue expanded by 22 percent in 2011, reaching a record $31 billion according to a report prepared by the Internet Advertising Bureau (IAB). They reported a 27 percent growth in search revenue to $14.8 billion and 35 percent expansion of display-related ads to $11.1 billion,
IAB’s data is similar to a January report by eMarketer, which also totaled U.S. digital advertising at $31 billion.
IAB’s outlook is a bit divergent from a report released in March by Kantar Media, which said fourth-quarter declines in the internet search and display sectors last year drove down the performance of the entire U.S. advertising market.
Meanwhile, smartphone device sales, users, and revenues are accelerating across the board. The sale of smartphone devices to new postpaid subscribers continues to grow, representing 48% of device sales as compared with 30% in the 2010 survey.
