TNS Media Intelligence/CMR predicted that the coming year will see a 5.1 percent increase in ad billings across media. That's about half the growth seen in 2004, according to BtoB Online. The second half of 2005 should see the lowest growth, as it will be compared to periods in 2004 when there was a presidential election and the Olympics. Where last year TNS predicted 21 percent online media growth, this year it is looking for only 11 percent, a proportional decline in growth in line with that seen in traditional media.
