ZenithOptimedia, the media buying unit of Publicis, blamed the downgrade on the lingering eurozone debt crisis and heightened tensions on the Korean peninsula.
ZenithOptimedia now says the advertising market in the eurozone will plummet by 3.9 per cent in 2013 instead of the earlier forecast of 1.6 per cent contraction. In 2012, advertising spending in the eurozone fell by 5.2 per cent from a year earlier.
Publicis is however optimistic for 2014 and 2015. The growth forecasts for those years were modestly raised to 5.1 percent and 5.8 per cent respectively.
ZenithOptimedia noted that advertising on hand held devices was "by far" the fastest growing segment with a 67 percent leap in spending expected in 2013 on the back of the tablet and smart phone explosion.
