“Very few TV programs mention gas prices when the nominal price is below $3.50 per gallon. Above this level, TV mentions of gas prices ramp up linearly, with each 50-cent increase in gas prices raising the coverage rate by 7.5 percentage points (p.p.). Alternatively put, while only 2.7 percent of transcriptions mention gas prices on average, 10.4 percent mention gas prices when the price hits $4.00, and 18.2 percent mention gas prices when the price hits $4.50.”
