From the back of Adam ’s pouch of Big League Chew:

Sitting in a bullpen one night 25 years ago, Portland Mavericks lefthander Rob Nelson, and teammate Jim Bouton, the former New York Yankee All-Star, wanted something really different and fun to chew. So they came up with a great idea - shredded bubble gum in a pouch - and called it Big League Chew. It soon became a hit with ballplayers everywhere. 

Over 450 Million Pouches later, Big League Chew celebrates its 25th anniversary! More and more professional and amateur players in all sports are turning to Big League Chew, a fun gum that keeps your mouth from getting dry when the game is on the line.

So now you know.

“Big League Chew is so soft it’s like slime in your mouth.” - Emily
