Millions will tune in Sunday for the Big Game: football, commercials or Taylor Swift?

LANSING, Mich. (WWMT) — Millions of Americans will be turning on their TV screens to watch the Big Game Sunday.

But the reasons may be vastly different: is it for commercials, football or the mega popstar expected to be in the stands?

Commercials are a big driver of viewership with advertisers putting big loads of cash toward a few seconds of screen time.

A 30-second commercial can come at a price tag of $7 million, according to Greg Gerfen, executive in residence for the advertising program at WMU Hayworth College of Business.

"Marketers are releasing in teasing,"Gerfen said. "They’re advertising early and releasing it on social media so the social media views and the sharing that people do with their teasers in their commercials before the Super Bowl even happens. It's another metric that they'll use."

But this year there is a new star in the stands: Taylor Swift.

Swift is expected to bring even more eyes to the commercials this year due to her high-profile relationship with Kansas City Chiefs tight end Travis Kelce, and Gerfen said she's having a big influence.

She has such a following of younger female audiences that they are coming to watch the game and so some advertisers that wouldn't normally advertise in the game actually advertising in the game," Gerfen said.

Makeup brands and popular drinks like "Poppi" are throwing money into the hat to get more viewers' eyes on their product this year.

San Francisco and Kansas City will face off at 6:30 p.m.
