Internet advertising revenue in the United States totaled $26 billion in 2010, including approximately $550 million for mobile ad revenue.

Online advertising is the foundation of the Internet economy, itself a vital component of the global economy. Advertising is responsible for the wealth of free and low-cost content and services available to consumers online including e-mail, news, television, movies, music and games. Policymakers should be cautious of imposing regulations that impact the principal funding mechanism of the Internet without taking a close look at a cost-benefit analysis of any proposed changes. In particular, privacy regulations that would restrict online behavioral advertising could undermine future growth in the Internet economy.
