ADOTAS – Despite the Olympics, China’s ad market growth has slowing down. However, the country is still making the numbers to potentially be the second largest ad market globally next year. Chinese ad growth will fall from 22% in 2008 to 19.5% in 2009, according to WPP’s media buying unit GroupM. Ad spending is anticipated to reach a total of $35 billion in 2008 in China. GroupM has said online advertising and marketing will be responsible for 7.3% ($2.5 billion) of that number.
