"American Idol" (8 p.m., Fox): Season 13 wraps with a two-hour finale in which either Caleb Johnson or Jena Irene will take a confetti shower. All we ask is that Caleb not beat another poor, helpless microphone stand to death. (For a recap of the finale, go to www.mercurynews.com/tv).
"Survivor: Cagayan" (8 p.m., CBS): The reality show will fork over $1 million to the castaway who did the best back-stabbing and blindsiding over a 40-day period. The two-hour finale will be followed by an hourlong reunion show. (For a recap of the finale, go to www.mercurynews.com/tv).
"Revolution" (8 p.m., NBC): It's true. "Revolution" will not be televised. At least not after tonight's episode. The lights go out on the apocalyptic drama, which has been canceled. Send your e-mails to NBC, not us.
"Modern Family" (9 p.m., ABC): As the season closes out, chaos mounts at the eventful wedding of Mitch and Cam (Jesse Tyler Ferguson and Eric Stonestreet). Of course. What else did you expect?
Also on Wednesday:
"The Americans," Season finale (10 p.m., FX)
