Why would the business owners of the product of Doritos chips make an an advertisement on the Super Bowl, rather than on a mainstream advertisement?
Here's an example of a Doritos chips advertisement on Super Bowl rather than a normal mainstream advertisement.
The Super Bowl is one of the most important sporting events in the world. It garners one of the largest TV audiences--for either regular viewing or sports. The networks command among its highest advertising rates for the Super Bowl. Sales in television sets go up dramatically during the weeks before the game--people want to watch it on larger, better screens. Super Bowl parties are numerous throughout the country. Snacks are purchased in abundance for the game, and many grocery stores routinely offer sales and two-for-ones for even greater purchase power. I purchased a Doritos party bowl years ago for the Super Bowl: It was a mini-replica of a stadium, complete with yard markers, green-colored turf, bowl seating, Super Bowl logo and separated raised sections for chips, dip, salsa, etc. After the game, I washed the party bowl and kept it with my other sports memorabilia. It may not be worth much, but it serves as a memory for the game and the party I held. As for the ads before and during the game, the Frito-Lays people probably recognized that advertising early in the game will serve as a reminder to eat their product, and there were probably thousands of viewers who headed to grocery stores and minute markets to purchase extra snacks at halftime of the game--providing increased sales for Doritos, no doubt the objective of the company's advertising.
