NEW YORK: Web researcher eMarketer has yet again revised down its estimates for 2008 US online adspend. It now says the total is  likely to be $24.9 billion (€16.6bn; £13.3bn), a slight decrease from its March prediction of $25.9bn.

Last October the firm was forecasting this year's total online adpsend at $27.5bn.

Despite the general economic gloom, eMarketer remains relatively upbeat on prospects for the market and believes growth of 17.4% is achievable in 2008: not bad but nowhere near the dizzy heights of recent years when the medium has enjoyed annual expansion of between 20% and 30%.

Says eMarketer senior analyst David Hallerman: "Even as the potent mix of a misfiring economy and consumers' changing media habits shave advertising dollars from traditional venues, such as newspapers and television, internet ad spending will continue to grow rapidly."
