It’s true: Drug companies are bombarding your TV with more ads than ever

Still, spending on direct-to-consumer ads is just a fraction of what the pharmaceutical industry spends marketing directly to health-care providers to prescribe their products. For instance, when drugmakers' direct-to-consumer marketing dropped to $3.5 billion in 2012, the firms spent $24 billion promoting their wares directly to doctors.
In 2011, television accounted for 52.6 percent of pharma's direct-to-consumer advertising dollars — in 2014, it was 61.6 percent.
