Mobile ad spending will exceed $6 billion worldwide by 2014, says Juniper Research, a slight revision upward from what it projected this past June. Despite that impressive figure, mobile ad spend will still represent a tiny slice of the total global ad pie — just 1.2 percent of all advertising dollars expected in that year. By that time, the character of mobile advertising will also change, Juniper says. For one thing, the traditional dominance of SMS ads will long be eclipsed by mobile ads on portals and mobile websites, though SMS is still expected to remain significant.
As an ad vehicle, the mobile web will hit its peak in 2011, Juniper says, in the face of the rise of Personal Messaging ads, of which SMS is a part. Personal Messaging also includes multimedia messaging (MMS) and instant messaging. Taken as a whole, the Personal Messaging category is expected to experience a cumulative annual growth rate of 64 percent over the next five years.
The chart after the jump provides a visual representation of how the various mobile ad channels will shape up through 2014.
