Abstract: A method for selling time-based inventory over a communications network includes permitting a seller via a graphical user interface to define a total time to be sold for a time based-inventory; permitting the seller via the graphical user interface to define a sales time interval amount smaller than the total time to be sold; dividing the total time as a function of the sales time interval amount so as to define a plurality of time intervals of the total time; and selling the plurality of time intervals via the communications network.

Abstract: A method and apparatus for generating a media campaign from information about available units stored in a central database, including a set of first characteristic data and associated behavior information and a set of media formats for the available units and associated behavior information. Selective criteria is entered based on the first characteristic data at a remote computer coupled to the central computer database via a network and web server for a search of the information stored in the database, and a search is generated based upon the selective criteria, the search identifying the certain behavior information corresponding to the first characteristic data and media format information associated with that certain behavior information. Results of the search are displayed at the remote computer, the results constituting matching media format information and associated information. The user then selects among the media formats from the search results to constitute the media campaign.

Abstract: A method and apparatus for displaying search results while generating a media campaign from information about available units stored in a central database, including a set of media formats for the available units and associated ancillary information. Selective criteria is entered at a remote computer coupled to the central computer database via a network and web server for a search of the information stored in the database, and a search is generated based upon the selective criteria. Results of the search are displayed at the remote computer, the results constituting matching media format information and associated ancillary information the results displayed according to the associated ancillary information, which preferably constitutes time periods for which the corresponding formats are available. The search results are preferably displayed in a timeline, preferably organized in daily or weekly views.
