This week eMarketer, a market-research firm, predicted that online-advertising spending in America, which makes up about half the global total, will increase by 8.9% in 2009, rather than the 14.5% it had forecast in August. The firm thinks search advertising will grow by 14.9% and rich-media ads by 7.5%, whereas display ads will grow by 6.6%. In short, online advertising will continue to expand in the recession—just not as quickly as previously expected.
