The act authorizing the dollar coin also provided for the Secretary of the Treasury to "adopt a program to promote the use of such coins by commercial enterprises, mass transit authorities, and Federal, State, and local government agencies." The Mint's initial advertising campaign, consisting of an estimated 1,600 television, radio and print advertisements and partnerships with the national retail chain Wal-Mart and the General Mills company, cost approximately $41 million. The television ads consisted of the head of George Washington superimposed upon a body, voiced by actor Michael Keaton, discussing the merits of the new dollar coin.
