Jerry Buhlmann, chief executive of Aegis Media, said: "Looking at the UK, forecasts have improved with significant signs of recovery in the TV market in particular where trends in the first quarter look positive. While the year ahead remains challenging, theses are encouraging signs."
Buhlmann said: "This early view of future global adspend shows the potential for modest recovery through this year and into 2011 in what looks like being an increasingly benign environment."
Carat is markedly more optimistic in its latest global adspend forecast for 2010, raising its prediction for the UK to 2.9 per cent growth from the 1.4 per cent it forecast in October.
The Aegis-owned agency expects a rise in global adspend of 2.9 per cent, up from its previous prediction of 1 per cent.
