Much of Asia will see as high as 14 percent growth in adspend in 2014, according to new figures by global agency Zenith Optimedia.

But the firm’s same data shows global radio share of adpsend is set to shrink from 6.9 percent (2013) to 6.3 percent by 2016.

Its ad forecasts split out Japan, Advanced Asia (Singapore, Hong Kong, Australia, New Zealand and South Korea) and Fast Track Asia (most other Asian countries and territories).

For Fast Track Asia, which includes India, China, Indonesia, Vietnam and the Philippines, ZenithOptimedia predicts growth of between 11 and 13 percent for the next three years.

After disappointing last year, Advanced Asia is projected to grow 4.9 percent this year, followed by 6.7 percent growth in 2015 and 5 percent in 2016.

Meanwhile Japan is expected to see growth hover around the 2 percent mark.

Globally, the agency forecasts that expenditure on mobile.

advertising, which stood at at US$13.4bn in 2013, will grow to $45 billion in 2016, meaning mobile will leapfrog radio, magazines and outdoor to become world’s fourth largest advertising medium.

The firm predicts worldwide internet advertising will overtake both newspaper and magazine advertising next year.

Newspapers and magazine revenue refers to all traditional printed editions.
