NEW YORK: Global adspend is forecast to climb 6% in 2007 and by a further 7% in 2008 to a total of $479 billion (€326bn; £235bn), according to a recent report from WPP Group's media operation GroupM.

Its This Year, Next Year study also predicts that adspend in the US is likely to increase by 2.8% though the current year and by 3.7% in 2008 - fuelled by the Beijing Olympics and the presidential election - reaching a total of some $168.6bn.

China is expected to see the largest proportion of new investment, slated for an an uplift of more than 20%. Brazil and Russia are likely to experience rises of 6% each; India, by contrast, is forecast to post growth of around 3%.

In terms of media, television is anticipated to account for at least 50% of next year's worldwide uplift. Online, which is projected to account for 30% of growth, is also expected to expand its share to over 10% of total global ad spend for the first time.

Sweden is predicted to become the first country where online is the largest single medium.
