here and chart below).
First, eMarketer's data are not specifically focused on the pharmaceutical industry. The data includes ALL healthcare industries, including doctors, hospitals and "other entities that deliver health services such as health maintenance organizations (HMOs)" and, I presume, health insurance companies. What percent of the $1.58 billion in online spending predicted for 2012 is pharma specific? Probably over 50%, but not 100%. Perhaps 75%? Your guess is as good as mine (or eMarketer's).
So the headline above is misleading. It should read "Healthcare Advertising Shifts to Digital." But is it really?
Another problem is that eMarketer's predictions about online healthcare ad spending have been "all over the map" by which I mean wildly inaccurate and meaningless. In 2007, for example, eMarketer predicted that the spending on online HC marketing would be $2.20 billion in 2011 (see here and chart below). But the eMarketer chart above now indicates the number is closer to $1.28 billion, which is quite a difference.
So, why should we believe eMarketer's prediction that online HC ad spending will increase by 23.3% this year? You tell me.
