THE world’s largest advertising group said key events such as football’s World Cup raised hopes for a “more stable year” in the battered industry.

WPP, headed by Sir Martin Sorrell, predicted gradually improving conditions in the media sector following an “encouraging return to stability”.

The trends that were first seen in November continued into January as like-for-like revenues remained largely flat on a year earlier, according to the firm.

This came as a marked improvement on the sharp declines in like-for-like revenues last year – up to almost 11% in the second quarter – which left 2009 pre-tax profits 11.3% lower at £663m.
