iPhone launches/Black Friday: In the earlier years of iPhone and iPad releases, there was a limited supply, encouraging a high demand for consumers to get there early to get the latest devices. The same idea is shown during Black Friday as consumers compete for discounted items. Both of these are an example of Game Theory, specifically the zero-sum strategy, as some customers "win" at the expense of someone else's "loss." This ultimately helped Apple gain more profits and brand recognizability.

Chick-Fil-A Campout Giveaways: Similar to the iPhone launch example, this is another example of a Zero-Sum game. Many potential customers camp outside Chick-fil-A in hopes of being one of the first 100 customers to receive free meals. The first 100 customers will receive free meals for the year, essentially allowing for a small subset of "winners" out of the large crowd of individuals waiting for the prize.

McDonald's Monopoly Game: In the earlier days of McDonalds, there was a monopoly game competition where customers competed against each other in return of the possibility of getting prizes. This is another example of the zero-sum game where one player's win was essentially another player's loss.
