Michigan Lottery and Sony Team Up for ''Sound Explosion''
Participants could enter the sweepstakes by sending four nonwinning tickets in an envelope with their name, address, and phone number.
A pre-promotion luncheon was held for media vendors participating in the promotion. Five Sony Discman players were raffled off at the luncheon. Radio, weekly newspaper ads, and point-of-sale displays in 6,500 Michigan Lottery outlets and 2,500 nonlottery outlets were used to generate statewide exposure for the "Sound Explosion Sweepstakes." A fuel tanker program was used to deliver a 20-second message at gas stations throughout the state.
