Warc, the marketing intelligence service, expects global advertising spend to increase by 4.3% in 2012 and by 4% in 2013 according to its latest international ad forecast
Russia (+14.6%) and China (+12.5%) are expected to be the fastest-growing ad markets in 2013, followed by Brazil (+9.5%) and India (+9%).
The US – the world's largest ad market with predicted revenue of $153bn in 2012 – is expected to expand at a slower rate of 2.5% next year without the benefit of certain big events.
Suzy Young, Warc's data editor, explained: "The global ad market has been boosted this year by quadrennial events, namely the Olympics, the US presidential election and, to a lesser extent, Euro 2012. Next year will suffer by comparison, with advertisers having fewer incentives to spend when the underlying mood is generally one of caution."
