the market for general Internet-wide navigation in competition with existing services. However, the new services or their technology could alternatively be acquired by an incumbent, thus making it available to users, or could focus on a niche that is not well served by the more general services.

So long as no single service becomes dominant, each competitor will have continuing pressure to improve its offerings. The net effect of these factors on innovation cannot be predicted.

Conclusion: The importance of the Internet as the infrastructure linking a growing worldwide audience with an expanding array of resources means that improving Internet navigation will remain a profitable goal for commercial developers and a challenging and socially valuable objective for academic researchers.

Conclusion: Since competition in the market for Internet navigation services promotes innovation, supports consumer choice, and prevents undue control over the location of and access to the diverse resources available via the Internet, public policies should support the competitive marketplace that has emerged and avoid actions that damage it.
