Advertising is a legal attack on your rivals and the advertising message is set by each player. The effect on the selected combination of target groups is then shown. Comparative advertising can be used to emphasize one's strengths. A great marketing campaign will make the individual branches better known. Very effective advertising also has a direct effect on the opinions and attitudes of the city's inhabitants. The better known your branches are, the wider your area of influence will be. This tempts the customers away from your rivals. You can also put posters up near rival branches to change the minds of hungry passers-by who were planning to give their money to your opponents.
