While the pace of growth is slowing, it remains significant, The Australian reported, as ad spending levels surged past the billion-dollar mark for the first time in 2006, a 61 percent increase over 2005. Online ad spending increased 34 percent in 2007.

Display ads made up 28 percent of the growth, while classifieds accounted for 26 percent. Search advertising remained at the top, and accounted for 46 percent, according to The Australian.

“As expected, the initial surge in interest and awareness of online which resulted in growth rates of 60 per cent plus has now eased to a more realistic and sustainable long-term growth pattern,” Patty Keegan, IAB Australia general manager, told The Australian.
