What only, companies not does for the sake of advertising their goods! So, in 1910, producer of cocoa "Van Houtens" promised to pay a large sum of money to one offender, who was sentenced to death. The purpose of transaction was an advertisement of the cocoa. Before the execution, the condemned shouted to the crowd: "Drink cocoa Van Houtens!". The advertiser honestly payed the promised money to the heirs executed.
Due to such a non-trivial advertising, this case made history. And the advertising campaign were not in vain: the sale of cocoa risen sharply.
