Global advertising spending will rebound to reach almost 450 billion US dollars by the end of 2010, and hit 500 billion dollars in 2012, the media buying group Zenith Optimedia forecast on December 6, 2010.

China, now the world's fourth largest advertising economy, will overtake Germany as the world's third-largest advertising market after the United States and Japan.

And markets in developing countries are predicted to grow much faster than developed markets, accounting for almost 36 per cent of all advertising spending by 2013, up from 31.5 per cent in 2010.
