Ad-Supported Internet Responsible for 5.1 Million U.S. Jobs, Contributes $530 Billion to U.S. Economy in 2011.

Between 2007 and 2011, when U.S. employment was very sluggish, the number of jobs that rely on the ad-supported internet doubled to 5.1 million, according to Economic Value of the Advertising-Supported Internet Ecosystem, a study commissioned by the Interactive Advertising Bureau (IAB). This shows the importance of this sort of advertising to not only to the internet economy but the economy on a whole. In light of studies such as this, it's important that policymakers do not over regulate internet advertising.
