An interactive computer system network enables a user to display desired information, such as news, financial and cultural information, and perform desired transactional services, such as banking and shopping, through any of a plurality of types of personal computers. User inputs are received by the personal computer and are translated into personal computer-independent data objects and executable code objects which are then processed by the network. These objects comprise partitioned applications required to process user inputs, portions of which are distributed and stored either locally within the personal computer or remotely in a host computer. User characteristics are monitored by the system in order to generate and display specific advertisements to the user based on individual usage characteristics and predetermined interests.
