Advertising groups issue dire slowdown warnings

LONDON/NEW YORK (Reuters) - Three of the world's largest ad groups have issued dire warnings about an industry slowdown, as economic upheaval throws planned spending on advertising from TV commercials to Web searches into doubt.

The forecasts from Publicis (PUBP.PA), Interpublic Group (IPG.N) and Aegis (AEGS.L) on Tuesday followed solid-third quarter results by each of the groups, showing they have so far weathered the storm.

But with economic troubles deepening, the advertising market is now at risk of suffering its biggest slowdown since 2001.

France's Publicis, the world's third-largest ad group by market capitalisation, reported third-quarter results in line with expectations but forecast a difficult end to 2008 and worse for 2009.

U.S.-based Interpublic Group, the world's fourth-largest, posted higher-than-expected quarterly profit and strong organic growth, but warned that the financial crisis had jeopardized marketing budgets.

Britain's smaller peer Aegis completed the trio, reporting solid organic growth before saying it could no longer predict how much companies would spend on advertising and was therefore cautious on its full-year outlook.

"We believe our industry will face a difficult end of 2008 and a marked slowdown in 2009," Publicis Chairman and Chief Executive Maurice Levy said.

Interpublic Chief Executive Michael Roth said the group was still set to achieve its 2008 financial goals but noted that the impact of the "increasingly unsettled and volatile business environment" on the sector was not yet clear.
