Today I’ll be testifying at a Senate Commerce Committee hearing on online privacy and commercial data collection issues. In my remarks, I make three primary points:

1. First, no matter how well-intentioned, restrictions on data collection could negatively impact the competitiveness of America’s digital economy, as well as consumer choice.
2. Second, it is unwise to place too much faith in any single, silver-bullet solution to privacy, including “Do Not Track,” because such schemes are easily evaded or defeated and often fail to live up to their billing.
3. Finally, with those two points in mind, we should look to alternative and less costly approaches to protecting privacy that rely on education, empowerment, and targeted enforcement of existing laws. Serious and lasting long-term privacy protection requires a layered, multifaceted approach incorporating many solutions.

The testimony also contains 4 appendices elaborating on some of these themes.

Down below, I’ve embedded my testimony, a list of 10 recent essays I’ve penned on these topics, and a video in which I explain “How I Think about Privacy” (which was taped last summer at an event up at the University of Maine’s Center for Law and Innovation). Finally, the best summary of my work on these issues can be found in this recent Harvard Journal of Law & Public Policy article, “The Pursuit of Privacy in a World Where Information Control is Failing.” (This is the first of two complimentary law review articles I will be releasing this year dealing with privacy policy. The second, which will be published early this summer by the George Mason University Law Review, is entitled, “A Framework for Benefit-Cost Analysis in Digital Privacy Debates.”)

Jerry Yang’s departure as Yahoo! CEO opens the door to a renewed bid by Microsoft to buy Yahoo!’s search business (or Yahoo! itself).  Such a merger could produce a significantly stronger challenger to Google in the search market.  With this possibility in mind, the WSJ just ran a fascinating history of the “paid search” business—the placement of “contextually targeted” ads next to search engine results based on the search terms that produced those results.

In a nutshell, Microsoft failed to see (back in 1998-2003) the enormous potential of paid search—just as small start-ups (such as Google) were starting to develop the technology and business model that today account for a $12+ billion/year industry, which is  twice the size of the display ad market and which supports a great deal of the online content and services we have all come to take for granted online.  Microsoft first put its toe in the water of paid search with a small-scale partnership with Goto.com in 1999-2000.  But this partnership failed because of internal resistance from the managers of Microsoft’s display-ad program.  In 2000, Google launched Adwords and thus began its transformation from start-up into economic colossus.  By 2002, Microsoft realized that it needed to catchup fast, and approached Goto.com (by then renamed Overture) about a takeover.  But Microsoft ultimately chose in 2003 not to buy the startup because  Bill Gates and Steve Ballmer “balked at Overture’s valuation of $1 billion to $2 billion, arguing that Microsoft could create the same service for less.” 

Microsoft, meanwhile, spent the next 18 months deploying hundreds of programmers to build a search engine and a search-ad service, which it code-named Moonshot. The company launched its search engine in late 2004 and its search-ad system in May 2006.

But Microsoft’s ad system came too late:

Advertisers applauded Moonshot for its technical innovation. But Microsoft had trouble coaxing people to migrate to its search engine from Google; advertisers were unwilling to spend large sums on MSN’s search ads. By building a new system instead of buying Overture, Mr. Mehdi says, “we really delayed our time to market.”

What’s most fascinating about the piece is that it seems to suggest that Microsoft missed its opportunities to get into paid search not because it was “dumb,” “uninnovative” or a “bad” company, but for the same sorts of reasons that big, highly successful and even particularly innovative companies fail.  The reasons companies generally succeed in mastering “adaptive” innovation of the technologies behind their established business models are the very reasons why such great companies struggle to encourage or channel the “disruptive” innovation that renders their core technologies and business models obsolete.  This dynamic was described brilliantly in Harvard Business School professor Clayton Christensen’s classic 1997 book The Innovator’s Dilemma:  When New Technologies Cause Great Firms to Fail.  (Read chapter one here and Tim Lee’s recent discussion of the book here.)  

Whatever one thinks about the debate over whether antitrust intervention is necessary to restrain Google’s growth, I’m sure we’d all applaud the evolution of increased competition in the paid search market through market forces.  Let’s hope that Microsoft—as well as Yahoo!—have carefully studied the vast literature produced by business schools in the wake of Christensen’s book about how big companies can avoid the Innovator’s Dilemma by promoting—and capitalizing on—radical innovation from within.  Indeed, this seems to be precisely what has guided Google’s own strategy as it has grown from “disruptive innovator” to become the very sort of behemoth that cannot easily escape the Dilemma, even if corporate managers are fully aware of the problem on a theoretical level.  If Google can do it, Microsoft should be able to, too.  But let’s also not discount the possibility that, no matter how hard Google’s management might try to retain the innovative culture of a start-up, the giant  can’t do that well enough to prevent its own apparent market dominance from being disrupted by new upstart innovators in search and advertising technologies.  

The head of Google Research talked about some of these possibilities in July 2007 and the Google has recently covered other possibilities.  Here are my own bets—for what little they’re worth—as to what such “disruptors” might be:

• Semantic search and social search – whichever search engine masters these tools will likely dominate the market for search, and thus search advertising.
• Micro-payments to search users for using a search engine and discounts for clicking on ads – something Microsoft has pioneered with its Cashback system but which is probably still only in its infancy.
• Behavioral targeting that can make display ads competitive with search ads by making display ads as relevant to consumers as search ads (or even more so), rather than simply trying to target display ads based on the context of a page—which limits the economic value of the ad “display inventory” that websites try to fill with ads, especially for smaller websites in the Internet’s “long tail” whose subject matter might have little relevance to the keywords for products or services that are more highly valued by advertisers.  
• Technologies that allow contextual targeting of ads in or around videos based on the contents of the video (and associated discussion by viewers in comments). Even the imperfect ability to automatically create transcripts of a video, and then search for keywords, could hugely increased the value of advertising associated with video content.

I suspect we’d all be at least a little surprised if we could see what search engines—and online advertising—really looked like in, say, 2019.  But I won’t be terribly surprised if Google—for all its ingenuity—ends up making some of the same mistakes Microsoft made with Search 1.0 ( c. 1998-2005).

The Progress & Freedom Foundation has just launched the new Center for Internet Freedom.  CIF offers an alternative to the proliferation of advocacy groups calling for government intervention online by offering timely analyses and critiques of proposals that diminish the vital role of free markets, free speech and property rights.  We aim to drive the Internet policy debate in new directions by emphasizing a layered approach of technological innovation, user education, user self-help, industry self-regulation, and the enforcement of existing laws consistent with the First Amendment.  Such an approach is a less restrictive—and generally more effective—alternative to increased regulation.  

Here are some of the issues I’ll be working on as CIF’s Director in conjunction with my esteemed colleagues Adam Thierer, Adam Marcus, and adjunct fellows: 

• Defending online advertising as the lifeblood of online content & services, especially in the “Long Tail”;
• Emphasizing market solutions to problems of privacy protection, especially regarding the use of cookies and packet inspection data;
• Protecting online speech and expression both in the U.S. and abroad;
• Defending Section 230 immunity for Internet intermediaries;
• Opposing online taxation and legal barriers to e-commerce and digital payments, especially at the state and local levels; and
• Ensuring that Internet governance remains transparent and accountable without hampering the evolution of the Internet.

Since the fall of 2008, a debate has raged in Washington over “targeted online advertising,” an ominous-sounding shorthand for the customization of Internet ads to match the interests of users.  Not only are these ads more relevant and therefore less annoying to Internet users than untargeted ads, they are more cost-effective to advertisers and more profitable to websites that sell ad space.  While such “smarter” online advertising scares some—prompting comparisons to a corporate “Big Brother” spying on Internet users—it is also expected to fuel the rapid growth of Internet advertising revenues from $21.7 billion in 2007 to $50.3 billion in 2011-an annual growth rate of more than 24%. Since this growing revenue stream ultimately funds the free content and services that Internet users increasingly take for granted, policymakers should think very carefully about what’s really best for consumers before rushing to regulate an industry that has thrived for over a decade under a layered approach that combines technological “self-help” by privacy-wary consumers, consumer education, industry self-regulation, existing state privacy tort laws, and Federal Trade Commission (FTC) enforcement of corporate privacy policies.

In an upcoming PFF Special Report, we will address the many technical, economic, and legal aspects of this complicated policy issue-especially the possibility that regulation may unintentionally thwart market responses to the growing phenomenon of users blocking online ads.

We will also issue a three-part challenge to those who call for regulation of online advertising practices:

1. Identify the harm or market failure that requires government intervention.
2. Prove that there is no less restrictive alternative to regulation.
3. Explain how the benefits of regulation outweigh its costs.

The Online Advertising Market

While there are other forms of targeted advertising based on who you are (“demographic”) or where you are (“locational”), the most important varieties are based on what you’re searching for, seeing or doing online at any particular moment (“contextual”) and the pattern of what you’re searching for, seeing or doing over time (“behavioral”). The bulk of Internet advertising falls into one or both of these last two categories, with behavioral advertising growing rapidly.

Search engines deliver contextual ads on search results pages based on the search keywords entered by a user, while third-party advertising networks (some of which also run search engines) deliver contextual ads on behalf of website operators who sell ad space to the network, with the ads displayed on each page chosen according to keywords on that page. Contextual advertising is far “smarter” than displaying the same “dumb” untargeted banner ads to every user, because the contextual ad uses keywords to “guess” what the user is interested in based on the context of each page. But the purely contextual ad network doesn’t “remember” what the user has looked at in the past, so its insights into what the user would find relevant are very limited, especially for some websites. Online behavioral advertising (OBA) solves this problem and increases the value of advertising space on all websites by targeting ads based on a “profile” of the user created by tracking websites the user has visited—as well as limiting the number of times a user is shown a particular ad.

The Perceived Harm Driving Calls for Regulation

For a decade, the basic technology behind OBA has changed little: When a user visits the typical webpage, they download not only the webpage contents but also a small piece of code that allows the website to distinguish that user’s browser from other browsers (a “cookie”)—without personally identifying the user. Some cookies are required to make sites work properly (“site cookies”) while others (“tracking cookies”) are used by the third party ad network in which that site participates to recognize that browser across multiple sites participating in the ad network, and thus create a “profile” of what the user might be interested in. Even though such profiles themselves are anonymous, many privacy advocates have pointed to four reasons why online profiling is becoming “too invasive:” (i) It is sometimes possible to infer the actual identity of the user; (ii) though all browsers allow users to opt-out of tracking by “cleaning out” their tracking cookies, a website may be able to restore deleted tracking cookies through the use of cookie alternatives such as “Flash cookies”; (iii) certain vulnerabilities in current browser design make it theoretically possible to “sniff” a user’s browsing history, cache or bookmarks; and (iv) the use of “packet inspection” by Internet Service Providers (ISPs) (instead of the use of cookies) to track online browsing amounts to illegal wiretapping.

The other concerns expressed by the advocates of regulation vary significantly. Some fear that browsing profiles could be captured by hackers, somehow associated with personally identifying information, and used for identity theft. These advocates demand limits on data retention as well as data security mandates. Others demand that users have access to their own profiles—a goal inherently in tension with data security. Most share a vague queasiness about “being tracked” and about advertising in general, while downplaying the effectiveness of self-regulation or user self-help.

Perhaps most legitimately, others fear that the real “Big Brother”—the government—will gain access to a “honeypot” of surveillance data that might be associated with individual users. A variety of other solutions have been proposed to what is, for the most part, a poorly defined problem, including a government-run “Do Not Track” registry to make it easier for users to block tracking cookies; mandating opt-in for some or all forms of profiling; and banning completely the collection of tracking data about sensitive subjects, cross-referencing of data sets, and use of packet inspection data for OBA.

The Less Restrictive Means: A Layered Approach

But how should policymakers decide which, if any, of these interventions are really necessary–or would even be effective? Ironically, those who demand immediate OBA regulation to protect user privacy are often the first to insist on less burdensome approaches whenever a policy “problem” involves purely non-commercial speech. For example, emphasizing personal and parental responsibility is often favored as the more sensible approach to dealing with free speech and child protection concerns. But, as Chapman University Law Professor Tom Bell has asked, why not apply the same standard across the board? Why not expect those especially privacy-sensitive users who object to OBA to do something about it? To the extent effective self-help privacy tools exist, they provide a means of solving policy problems that is not only “less restrictive” than government regulation but generally more effective and customizable as well. Why settle for one-size-fits-all solutions of incomplete effectiveness when users can quite easily and effectively manage their own privacy? Indeed, those who advocate personal responsibility and industry self-regulatory approaches to free speech and child protection issues should be advancing the same position with regards to privacy.

Fortunately, a wide variety of self-help tools and “technologies of evasion” are readily available to all users and can easily thwart traditional cookie-based tracking, as well as more sophisticated tracking technologies such as packet inspection. While cookie management tools that allow users to delete their cookies have been standard in browsers for some time, the latest generation of browsers incorporates far more advanced control over what kind of cookies browsers will accept from websites in the first place. Furthermore,  the extensible nature of modern browsers allows any freelance software developer who sees a way to improve a browser to do so by writing an add-on that “plugs in” to the browser using standard programming interfaces designed by each browser developer.  Many such add-ons are wildly popular, but even those users who never install a single one benefit from the acceleration of browser evolution made possible by add-ons.  We will be documenting examples of these tools in our upcoming Special Report and in an ongoing  series of blog essays.

The Benefits of Smarter Advertising

The “free” Internet economy is based on a simple value exchange: Users get access to an ever-expanding collection of content and services at no cost from websites that are able to generate revenue from “eyeballs” on their pages by selling space on their sites to advertisers, usually through ad networks. The smarter that advertising, the more free content and services it can support. This is the same value exchange that has supported free, over-the-air television and radio content for decades. The only difference is technological: Because websites can connect directly with the user, they need not rely on crude profiling tools such as Nielsen ratings.

There are larger economic benefits of smarter online advertising. First, it makes the overall economy more open and competitive by allowing small market entrants to reach consumers with messages about their products. Second, those who attack the use of packet inspection by ISPs for OBA fail to see that it is precisely the kind of “game-changer” that could disrupt Google’s currently dominant market position. Third, the involvement of ISPs in OBA could help defer broadband costs: Even if OBA revenue does not completely subsidize monthly service costs, smarter advertising could at least keep prices in check and potentially lower them significantly going forward.

But smarter advertising isn’t just about selling products or services. It is ultimately about making all kinds of speech more cost-effective. The ability to “target” listeners more narrowly also increases the ability of political and other not-for-profit speakers to communicate their messages. In short, smarter advertising means more voices, more choices, and more speech. The line between “advertising” and “content” is already blurring rapidly, as the technologies used to customize advertising are also used to customize webpages and ad networks themselves are used to deliver content.

The Larger Implications of Potential Regulation

As if reducing the advertising revenue generated by each web ad didn’t do enough to reduce the total amount of funding for free web content and services, government regulation of targeted online advertising could reduce advertising revenues even further by aggravating the problem of adblocking in two ways. First, the less relevant ads are, the more annoying users will find them, and the more likely users are to try to block them. Increased relevance is perhaps the most important remedy for adblocking and the best way to maintain the implicit value exchange that currently supports free Internet content and services

Second, regulation could short-circuit the eternal battle of technological one-upmanship between online advertisers and those users who rely on the technologies of evasion to “opt-out” of seeing ads or being tracked. Such privacy-conscious users are “free-riding” off of those users who don’t opt-out, since (at present) they generally don’t lose access to the free content and services supported by the targeted advertisements that other users do see. The user who blocks tracking, but not ads, is still free-riding off those users who don’t opt-out of tracking. On a large enough scale, such self-help has the potential to disrupt the value exchange of the Internet, just as automatic commercial-skipping has already disrupted the value exchange of television. As with all “Spy v. Spy” battles, this long-term trend is inevitable: As more sophisticated technologies of evasion are incorporated seamlessly into browsers and can be used without significantly degrading the browsing experience, their use will become increasingly mainstream. But ultimately, just as with television commercial-skipping, market forces can and will, if permitted, respond through technological means and the development of new business models. Today’s implicit quid pro quo may become, of necessity, explicit: Websites and ad networks will have to find increasingly creative ways to grant access to certain content and services for users who do not block ads or the tracking that makes ad space more valuable. Policymakers should take care not to ban such technologies or cripple such business models (e.g., through requiring opt-in), which may rely on more sophisticated forms of targeting such as the use of packet inspection data.

As users face an increasingly clear choice between (i) getting content and services for free supported by behavioral advertising and (ii) paying to receive those same services and content without tracking or even without ads altogether, policymakers will finally see whether users are really as bothered by profiling as the advocates of OBA regulation insist. Given the ongoing and widespread replacement of fee- or subscription-supported web business models with ad-supported models, it seems likely that the vast majority of consumers will continue to choose ad-supported models, including profiling.

Conclusion

The questions raised above—about the harm that supposedly requires intervention, the availability of less restrictive means, and the cost/benefit analysis of regulation—are vital considerations for the future of the Internet. Indeed, if smarter online advertising will not fund the Internet’s future, what will? As both the desire for “free” services and content and the need for bandwidth expand, OBA has the potential to offer important new revenue sources that can help support the entire ecosystem of online content creation and service innovation, while also providing a new source of funding for Internet infrastructure and making ads less annoying and more informative. That would certainly seem preferable to increased user fees or other “pay-per-view” pricing models for Internet content and services.

But looming legislative and regulatory action could stop all of that by replacing the current regime—in which the FTC merely enforces industry self-regulatory policies—with one in which the government preemptively dictates how data may be collected and used. The more enlightened approach is a “layered” approach to privacy protection that combines industry self-regulation, enforcement of industry-established privacy policies, consumer education, and user “self-help” solutions. These and other issues will be addressed in greater detail in our upcoming PFF Special Report.
