Taylor Swift set to bring in millions for the NFL and the Kansas City Chiefs this season

Singer and songwriter Taylor Swift is the biggest pop star in the world right now, making $13 million in ticket sales each night of her lauded Eras tour, according to fortune.com.

Swift has 274 million followers on Instagram and a loyal fanbase called the 'Swifties.' With so many fans, Swift has a unique place in the business world.

In recent weeks, Swift (the biggest popstar in America) has been seen watching the NFL (the biggest sport in America), bringing the NFL more eyes than ever before.

Swift was spotted at Arrowhead stadium watching the Kansas City Chiefs versus Chicago Bears, reportedly to see Chiefs tight end Travis Kelce play.

The sport is the biggest in America, but it has tried several campaigns to entice different groups of people, like Latinos, who are statistically more interested in soccer than the NFL.

More viewers and fans equal more revenue for the NFL to make, and the appearance of Swift at the recent Chiefs games has increased the viewership.

For Kansas City's game against the New York Jets on Sunday Night Football, the game averaged 27 million viewers, the second highest this NFL season.

What's more shocking is that due to Taylor Swift's appearance at the game, viewing among girls from 12-17 was up 53% higher than the season's first three NFL Sundays.

As well as the viewership in girls going up, women 18-24 were up 24%, and women over 35 were up 34%, giving the NFL a free campaign to reach a new demographic they have been searching for.

For the Kansas game against the Jets, ticket prices had jumped from $83 to $119, a 40% increase due to Swift's attendance.

The Kansas City Chiefs played the Minnesota Vikings on Sunday, and ticket prices went up before Taylor Swift confirmed if she would be there.

Swift was seen with Travis Kelce's mom at the Kansas versus Chicago game, and the effects this has had on Travis Kelce and the Chiefs is huge.

Kelce's added over 400,000 new followers to his Instagram profile, while Stubhub has reported a threefold increase in Chiefs ticket searches.

Fanatics have reported the sale of Travis Kelce's number 87 jersey has increased by 400%, putting him in the top five player sales.

The NFL has been targeting women and young girls for a while with little success, with 42% of women in a survey saying they were not fans of the sport at all.

The welcome arrival of Taylor Swift at NFL games has led to an increase in women fans, women buying jerseys, and ticket prices rising, helping the NFL more than any other marketing campaign they had created before.
