So this is not to speak about the rigged promotional games mentioned by OP but my Uncle won many large prizes in the 80's(corvette, boat, jaguar) through promotional giveaways. I remember my Dad told he his plan was to go to multiple places where a promotion was happening(he lived in LA and there were alot of them in that area) and filling out hundreds and even thousands of submissions to game the odds in his favor. It worked for him and I think others were doing this as well as now most promotions like this limit submissions to one entry per person(or family). And most car giveaways today are scams anyways just to get your info to marketers, but in the 80's things were different and people who knew about gaming probabilities could and did win many large prizes.
