BANNER ADVERTISING DISPLAY SYSTEM AND METHOD WITH FREQUENCY OF ADVERTISEMENT CONTROL

An Internet advertising system has a database, a controller, and an ad server operating as part of a web server. The database has advertising campaign information, including identification information and frequency information for how often the ad is to be served. The ad server uses the campaign information from the database to control the relative ratios of serving ads, the distribution of ads throughout the day, and any triggering mechanisms for controlling what ads are served.
