The idea of software that can be downloaded from the Internet is not new, since components and distributed objects have been around for several years. Equally important, new business models make the e-services vision more likely than ever before. Examples of e-services today are abundant.
Web sites are no longer self- contained entities.
Besides connections to live data, most sites use advertising banners and stock quote look-ups, passing users back and forth to other Web sites and services. This trend will continue as Web sites continue to become made up of services. In addition, a more distinct form of e-services will emerge as specific, online information and application services become increasingly available to users. This will require business models that leverage delivery of the service as the primary motivation for consumers to adopt devices and to associate with specific companies. One potential business model combines service delivery with a contract for long-term service.
