Reba McEntire will be host of The 39th Annual Academy of Country Music Awards (7 p.m., CBS) from Las Vegas. Eleven awards honoring the past year’s elite in country music will be handed out during the three-hour ceremony, including Entertainer of the Year, Top Male Vocalist, Top Female Vocalist, Top New Artist, Top Vocal Group, Top Vocal Duo, Single Record of the Year, Song of the Year and Album of the Year.

Past winners and contenders, including McEntire, Martina McBride, Toby Keith, Montgomery Gentry, Lonestar, George Strait, Keith Urban, LeAnn Rimes and Rascal Flatts, will be on hand to perform, present awards and compete for new ones. The Rock and NASCAR personality Sterling Marlin also will present.

• The series “TV Revolution” (8 p.m., Bravo) concludes with “Body Count,” an hourlong look at the evolution of small-screen violence. “Count” covers the depiction of carnage on the news, from the “living room” newscasts from Vietnam to the terrorist attacks of Sept. 11, 2001.

The hour gives equal time to the mayhem on episodic television, featuring clips from “Starsky & Hutch,” “Hill Street Blues,” “NYPD Blue,” “The Sopranos” and “The Shield.”
