If the difference between local- and long-distance access continues to widen, broadband users may well spend more and more time sampling the higher-quality, but much more limited, content offered locally by the provider rather than suffer the lower speeds of the open Internet. The prospect of last-mile "super broadband" services that combine the visual quality of television with the interactivity of the Web is attractive to broadband providers, big media companies, advertisers and many consumers. Others see these "walled gardens" as a threat to open competition and diversity (see "Web Behind Walls").
