When it debuted, McDonald's "Monopoly" game was a huge deal and people would eagerly open their tickets to see if they won a big prize. If they won it was usually a small fries or another ticket, but sometimes it was some money and one person won $1M.

After a while the luster wore off and it faded into the background. I'm sure it boosted sales in its first few years quite a bit but now you hardly hear about it. I'm actually surprised it still happens.
