Super Bowl: a global show between Chiefs and 49ers under the eyes of Taylor Swift in Las Vegas. A record 67.8 million Americans, about a quarter of the country, will bet on the match, enough to generate the indecent sum of $23.1 billion.

The meeting should break all records, particularly for viewers (115.1 million last year), who will be able to attend the famous half-time concert, given this year by the rapper Usher. The Chiefs, winners last year against Philadelphia Eagles, would be the first to keep their trophy since Tom Brady's New England Patriots.
