In 1968, the ACM Awards honored Glen Campbell and his record Gentle on My Mind with the very first Album of the Year award. Since that day, 50 years ago, Album of the Year has remained one of the most coveted titles awarded at the ACMs.

While Campbell won the award for a second year in a row (alongside Bobbie Gentry) in 1969, the history of ACM Album of the Year is diverse and storied. You might be surprised, for example, to learn that oft-nominated artists such as Vince Gill and Little Big Town have never managed to walk away with the title. Or that George Strait and Alabama were tied for the most category wins (three each) until Miranda Lambert broke their record when she won her fourth Album of the Year title, for Platinum, in 2005. (She's since cemented that record by taking home a fifth category win, in 2017, for The Weight of These Wings.)

On April 15, the ACM will hand out its 51st Album of the Year award. Will the winner be Chris Stapleton for the second time, or will Little Big Town, Jon Pardi, Old Dominion or Thomas Rhett walk away with their first Album of the Year trophy? Fans will have to tune in to find out, but first, let's take a walk down memory lane. Click through the photo gallery above to see every ACM Album of the Year winner ... ever.

The 2018 ACM Awards are set to take place in Las Vegas, Nev., and air live on CBS beginning at 8PM ET. The ceremony will take place at the MGM Grand Garden Arena.
