Once upon a time not so long ago the online advertising medium was expected to continue to enjoy its new-kid-on-the-block status and continue a growth pattern measured in double digits. But according to a revised projection, it’ll just barely be staying in the black, according to an article by paidContent.org. In December, Barclays Capital expected online would grow +6% — and that was a marked reduction from the +16% it expected just two months earlier. Now it’s calling for growth of only +2.3. It’s looking for a modest online rebound to +5.7% in 2010.
