A 50th anniversary is a big one to celebrate, so the Academy of Country Music is going big for this year's celebration on Sunday, April 19. In addition to moving the annual awards ceremony to the massive AT&T Stadium outside Dallas, the ACM will present Garth Brooks, Kenny Chesney, Miranda Lambert, Reba McEntire, George Strait, Taylor Swift and Brooks & Dunn with the 50th Anniversary Milestone Award during the telecast. Renowned silversmith David Yurman designed the special 50th anniversary trophies, which will recognize special achievements unique to the ACM.
