To increase efficiency and impact of marketing

Repetition is so often the key to success in marketing. If you have a limited amount of time to reach your audience, using several forms of media increases the saturation and repetition rates on a compressed schedule. This is seen most in event and sale promotions. Newspaper ads, direct mail, websites, radio and television ads can all work together seamlessly. Timing for the various media is usually best done simultaneously, but can be worked to optimize feedback mechanisms, for instance, through reply post cards.
