The "Silver Bullet" (as it's known to fans) first hit shelves in 1978 as part of the "light beer wars" of the era, when competitors like Miller Lite and Natty Light also broke onto the scene.

It was honed for decades before its debut, and today, Coors Light boasts an Instagram profile with hundreds of thousands of followers.
