KALAMAZOO, MI -- After 33 years, Buster Bronco is switching to Pepsi.

WMU will be switching from Coke to Pepsi on its campus.

As of August, Western Michigan University will be serving Pepsi Co. products throughout its campus, including in the Bernhard Center, Waldo Stadium and at sporting events, a university spokeswoman said.

The switch came about as a result of a competitive bid process, said Cheryl Roland, executive director of university relations.

Coca-Cola had been WMU's vendor for 33 years, according to Eric Telligrini, unit sales manager for Pepsi Kalamazoo.

Pepsi Co. products include Mountain Dew, Gatorade, Lipton, Cheetos, Quaker, Lays, Cheetos, Doritos and Tropicana.

"It was definitely kind of a underdog story," said Telligrini. "It's a big deal for us."

The contract is for seven years, with a three-year renewal option. Telligrini said that university's population of an estimated 25,000 to 27,000 people campuswide would be the largest exclusive contract the Kalamazoo team had ever serviced.

"There's not a bigger customer or bigger account that we have," Telligrini said. "Our 90 employees are excited to have a great partnership."
