You're saying there is no other event that Dorito's could possibly use an ad about "The Big Game" for? That's incorrect, and that's my point.
Why make an ad you can only use once, when you could easily tweak it and be able to reuse it? Like you said, its not like anyone won't know you mean the Super Bowl, when you're talking about the big game on Super Bowl weekend.
Can you show me any ad, from any time, for any product, that refers to "the big game" meaning the superbowl and then, after tweaks, refers to some other big game?
