A third of mobile ad cash is spent on search ads

More than 34% of all mobile advertising money is being spent on mobile search advertising, according to figures from Juniper Research. They say mobile search advertising spending in 2008 will exceed $445 million (£226 million) - and it'll increase to over $2 billion by 2013, with the total spending on mobile ads hitting $7.6 billion (up from $1.3 billion in 2008). ABI Research published a similar report last month.
