Advertising Age has published Ad Spending numbers for measured media in April 2007. According to the release:

U.S. measured spending in April 2007 rose a weak 0.6%, with improved results for network TV but a continued poor showing for newspapers. April's gain compared to a 2% increase in March, 4% decline in February (which lacked the year-earlier Olympics windfall) and 0.5% rise in January. Measured spending over the most recent 12 months was up 2%. Ad tracker TNS Media Intelligence forecasts a 1.7% increase in 2007 U.S. measured media ad spending.

The biggest losers were radio (36M), network tv (598M), newspapaer (993M). Total spending was up (2.79B) with internet leading the way (1.47B).
