While eMarketer is expressing some doubt as to mobile entertainment’s health this year, its forecast for online ad spending in 2007 is anything but: it expects growth to exceed $20 billion.
In particular, Mediaweek points out, the top portals, Google, and top social networking hubs are likely to reap the most benefits—that is,  if they can weather further co-opting by marketers, which tends diminish their value in consumers’ eyes.
To put it all in perspective: online advertising continues to grow very quickly—ZenithOptimedia recently forecast that global Internet advertising spending would grow 28.2 percent in 2007 compared to growth in other media of 3.9 percent—but its share of the overall advertising pie remains relatively small. The $24.4 billion spent on Internet advertising in 2006 is just 5.8 percent of global advertising spending of $423.8 billion, according to ZenithOptimedia, which expects that share to rise to 7 percent this year.
