The record-holding annual viewership of the Super Bowl leads to record-setting investments in the half-time advertisement slots every post-season.
At $5 million (£4 million) per 30 seconds these days, some would argue that they are the riskiest of advertising Hail Marys, but sometimes they pay off.
Occasionally they are so eye-poppingly funny, so eye-wateringly adorable, so effortlessly catchphrase-worthy that they steal the half-time show itself.
So, what does it take to win the Super Bowl in the world of advertising? Let's take a look at 20 of the best ever big-game ads:
