Commerco start point portal sites are developed to serve a network of companies related to, in this case, SatelliteRadio. Commerco views start point portals as a metaphor for business districts. As in the real world, some districts, like malls, are focused more to consumers, while others, like financial districts, tend to be more a gather place for business. Because the Internet is not a physical place, there are many more resources than time to find, visit and remember them. These resources are also distributed all over the world, which makes developing start points for a given resource, a logical concept.
Search engines do a tremendous job of gathering all Internet resources.
Commerco portals are simply a subset of these focused upon sites that do electronic commerce. Net site will relate to topics relevant to its name. To better focus this general term, vertical market portals under SatelliteRadio. Net will focus attention to a more specific or related area of interest. Commerco sites operate on either an affiliate relationship basis or on a membership basis, if an affiliate program does not exist.
