Forrester: Interactive Marketing To Grow 11% To $25.6 Billion in 2009

Forrester Research predicts that interactive marketing spending will hit $25.6 billion this year -- up 11% from $23.1 billion in 2008, despite being flat, as marketers shift money from traditional media to digital channels.

That total, which also includes search, email, social media and mobile marketing dollars, is expected to more than double to nearly $55 billion by 2014.
