<P>PROBLEM TO BE SOLVED: To provide appropriate methods for presenting forced advertisements to television viewers. <P>SOLUTION: Methods and systems for forced advertising are provided. These methods and systems determine when a forced advertisement is to be presented, determine what forced advertisement is to be presented, and control how the forced advertisement is to be presented. A forced advertisement may be received prior to the time at which the forced advertisement is to be presented or when needed. The forced advertisement may be presented when certain broadcast advertisements are being broadcast, at certain times of the day, or at certain times within a program. The forced advertisements may be selected on the basis of content of a replaced broadcast advertisement, content of a nearby program, or independently of any broadcast-related factors. Finally, forced advertisements may be presented so that a television viewer can not escape viewing the advertisement by changing channels or turning off the television. <P>COPYRIGHT: (C)2008,JPO&INPIT |
