EMarketer has revised its online ad spending forecast downward, predicting a drop of 2.9% to $22.8 billion. eMarketer's previous prediction for 2009 was $24.5 billion -- a growth rate of 4.5%. According to eMarketer calculations based on Internet Retailer data, 56.8% of U.S. online retailers maintain a Facebook presence, 41.4% are on YouTube and 28.6% use MySpace. Only 20.4% are on Twitter. Twitter is a hotbed of experimentation for retailers that see it as a channel for customer service, promoting the deal of the day and more. As people spend more time on various social networks, retailers feel pressure to be there as well.
