A SYSTEM AND METHOD FOR GENERATIONG A LIST OF SUGGESTED SCHEDULED TELEVISION PROGRAMS WHEREIN TELEVISION SCHEDULE GUIDE DATA WHICH COMPRISES CHARACTERISTICS OF SCHEDULED PROGRAMS AND OPTIONALLY RELEVANCY OF THOSE CHARACTERISTICS IS OBTAINED FROM BROADCAST INFORMATION. USER PROFILES COMPRISING CHARACTERISTICS OF TELEVISION PROGRAMS PREVIOUSLY VIEWED, THE CUMULATIVE AMOUNT OF TIME PROGRAMS HAVING THOSE CHARACTERISTICS HAS BEEN PREVIOUSLY VIEWED, AND OPTIONALLY THE RELEVANCY OF THE PREVIOUSLY VIEWED CHARACTERISTICS IS STORED. THE USER IS ALLOWED TO MANUALLY ADJUST THE WEIGHTS ASSIGNED TO CHARACTERISTICS SO AS TO OVERRIDE THE SYSTEM ASSIGNED WEIGHT VALUES. THE SYSTEM CALCULATES THE SUGGESTED PROGRAM LIST FROM THE SCHEDULES IT RECEIVES FROM BROADCAST OR OTHER MEANS, USING THE CHARACTERISTICS WEIGHTS IN THE USER PROFILES. THE USER INTERFACE DISPLAYS PERCENTAGE VALUES CURRENTLY ASSIGNED TO CHARACTERISTICS IN THAT USER''S PROFILE, BUT SMOOTHES THE PERCENTAGE VALUES BY CALCULATING THEM BASEDON A RATIO OF CHARATERISTICS WEIGHTS TO THE GREATER OF A PRESET VALUE SUCH AS 500 OR THE ACTUAL WEIGHT OF THE HIGHEST WEIGHTED CHARACTERISTICS IN THAT USER''S PROFILE.(FIG 3)
