Those of us in communications better pay attention to the ads during the SuperBowl. According to Nielsen, 58% of global spending on advertising is still invested in that mature medium. The growth of the spending is what is low: 4.3% in 2013.
On the other hand, there is a 32.4% increase in the spending on web, mobile and app advertising. But that only represents 4.5% of overall global ad spending. Here is the coverage in Tech Crunch.
Meanwhile, in those other mature mediums - radio, print, newspapers and cinema - ad spending declined in 2013. Outdoor was the exception. It had 5.1% growth.
