CBS Corp. (NYSE: CBS) Chief Research Officer Dave Poltrack took dead aim at a Forrester Research survey that said marketers consider TV ads less and less effective. AdAge was there to capture Poltrack’s fit of pique. He was particularly set off by advertisers’ claim that only 41 percent of their media budgets went to TV last year versus 58 percent in a 2008 survey. Poltrack called those figures here “bullsh*t numbers.” He added, “For that to happen, if advertising dollars during the recession went down 10 percent, TV advertising would have been down 30 percent. Everyone knows that didn’t happen.”
