The Interactive Advertising Bureau reported 2007 figures today on digital advertising, and not surprisingly the growth is healthy and ahead of growth in other spaces: up 26 per cent to a total of $21.2 billion U.S. That's a record sum, but not growth on the same scale of the previous year.
The fourth-quarter of 2007 was itself a record: $5.9 billion and a 24 per cent growth over the same quarter a year earlier.
What's interesting is how static particular advertising categories looked in 2007 against 2006. The IAB release didn't suggest any particular boom or bust in ad categories, although the data hint that rich media (video) is on the rise.
