"Game of Thrones" (9 p.m., HBO): Let the Game begin. The horrific events of last year's Red Wedding figure to cast an ominous shadow over Season 4 of the fantasy epic. Now Arya (Maisie Williams) and what's left of the Stark family are vowing bloody revenge on the Lannisters, who are preparing to marry off bratty king Joffrey (Jack Gleeson). Meanwhile, Daenerys (Emilia Clarke) and her army continue their slow-but-steady march through the desert. And the saga, like Dany's dragons, is bigger and badder than ever.

"49th annual Academy of Country Music Awards" (8 p.m., CBS): Blake Shelton and Luke Bryan return as hosts of the 49th annual Academy of Country Music Awards because, lord knows, these singers don't have enough trophies. Among the performers are Jason Aldean, Toby Keith, George Strait and -- huh? -- Stevie Nicks.
"Turn" (9 p.m., AMC): This new drama is about courageous American spies during the Revolutionary War. You probably never heard of these guys, but without them we might not be shooting off firecrackers every Fourth of July.
"Silicon Valley" (10 p.m., HBO): Can computer geeks make us laugh? We're about to find out with this new tech-centric comedy from Mike Judge ("King of the Hill"). It follows a painfully shy brainiac (Thomas Middleditch) and his pals as they produce a killer new algorithm that finds them caught between feuding billionaires.
