Barbara van Schewick, Assistant Professor at the Stanford Law School, introduced the current debate about net neutrality and explored the implications for diversity and freedom of expression online.

Network providers were at one time ‘application blind' - they were unable to see what was contained in the data packets that allow information to be transmitted online. Now that this is no longer the case, a debate has emerged about the role for regulation in controlling the ability of network providers to block or interfere with applications. What was drawn up as a voluntary policy statement is now being considered and revised by the FCC's Open Internet Proceeding.

Blocking of applications is problematic on several counts. First, there may be incentives for network providers to block applications that threaten their own profitability (for example, Skype). This leads to a situation where the success of applications is no longer decided on user criteria and the overall value created for society diminishes. Second, the great promise of the internet is that it removes traditional gatekeepers (such as mass media outlets) to speech. This is undermined if network providers have the ability to control what content users see. This is particularly problematic since users cannot easily switch to another provider as they could if a particular store did not carry a product they wanted. The cost of switching makes this impractical and in places without a choice of providers, this is not an option.

In drawing up regulation against blocking the FCC is debating a number of related issues:

Discrimination: Even if blocking is prohibited, discriminating between levels of service can still allow network providers to slow down an application to the extent that it becomes un-useable. This is actually a more effective tool than blocking since it is much harder to detect. Users may attribute slow speeds to poor design and potentially useful applications will fail to get traction.                                                                                                                                                                                                                                                                                                                                                                                                                              

Charges for different levels of service: Even if we agree network providers should not discriminate between the services they provide in an arbitrary way, could they offer improved service for payment? Opponents argue that this policy would be bad for competition since new developers would be unable to pay for the levels of service that established players could afford. And it would threaten the ability of poorly resourced minority voices - e.g. small NGOs and publications - to get heard.

Exceptions to discrimination: Network providers argue that there needs to be some discrimination to allow them to undertake reasonable network management. But it is difficult to determine what counts as reasonable management. One concern is that peer to peer networks - which allow those without many resources to exchange material cheaply - might be targeted in particular, since they can create a lot of congestion. This might also threaten the ability of new applications with high bandwidths to get funding, since the risk of being slowed down by the networks would be perceived to be too high by investors.

Many of the major benefits of the internet - the ease of publishing and coordinating, for example - are only possible through applications. Hence the outcome of this debate will have serious implications for the future social and political impact of the internet. 

Megan Smith, Vice President, New Business Development and General Manager, Google.org., argued that greater interconnectedness achieved by information technology is a major liberating force in the world. Whether it is aiding the coordination of protests or increasing transparency of governments, the exchange of information has huge benefits. This is not a new phenomenon. In places where people have been able to exchange information easily, social progress has followed. Megan cited the example of Seneca Falls, New York where the canal system allowed for extensive communication; it became significant in both the women's rights and abolition movements.

While a large proportion of the world is benefiting from greater interconnectedness, Africa still lacks the infrastructure to take full advantage. Submarine fiber optic cables are necessary for quick and cheap internet cables and many African countries, particularly in the east, are not connected to these, relying instead on satellites. This is likely to change over the next few years, bringing great potential for further development.

The mission of Google.org is to use technology to drive solutions to global challenges such as climate change, pandemic disease and poverty. The organization was set up as part of a commitment to devote approximately one percent of Google's equity plus one percent of annual profits to philanthropy, along with employee time.  Google.org now places its strategic focus on those projects that can leverage the resources of Google staff, particularly its engineers.

Current projects that harness the power of information include:

• Google Flu Trends: This uses aggregated Google search data to estimate flu activity up to two weeks earlier than traditional methods. This system has almost 90% accuracy in real time flu prediction and is therefore an extremely useful tool for health delivery agencies. It is now being used in 30 countries. Google is also starting to work in Cambodia to collect data around SARS.
• Google Power Meter provides a system for consumers to understand their in-home energy use and to take steps to reducing this. The Meter receives information from utility smart meters and in-home energy management devices and visualizes this information on iGoogle (a personalized Google homepage).The premise underlying this project is that greater information is going to be crucial to tackling climate change and consumers ought to be able to be empowered to make informed decisions about their energy use.
• Disaster relief: In response to the Haitian earthquake, a team of engineers worked with the U.S. Department of State to create an online People Finder gadget so that people can submit information about missing persons and to search the database. Google Earth satellite images have also been used to document the extent of damage.
