Today I went to the grocery store and they took a somewhat creative approach. While the grocery store chain isn't an "official sponsor" of the NFL or the Super Bowl, Frito Lay and Pepsi are. Immediately when you walk into the store, there are 2 very large, full height displays of the usual stuff on sale for a game-watching party - pre-made heat and eat pizzas, chips, soda, beer, sandwich, cheese and veggie trays and the like...And above those displays they have several large signs that say "We have you covered for your Super Bowl LVII party needs", and the Super Bowl logo is on prominent display . In the middle is a big sign that has the Frito Lay and Pepsi logos, and a big NFL crest with a sign saying "Official Sponsors of the NFL and Super Bowl LVII".
So while the grocery store isn't a sponsor, those soda and snack chip brands are, and the store simply piggy backed off that, created a display I'm assuming with their blessing and that's the first thing customers see when they enter. Problem solved, and no need to skirt around and use the name "Big Game".
