Want proof that there are simply too many new series, channels and streaming services to follow? The series “Grace vs. Abrams” (10 p.m., A&E, TV-14), featuring Dan Abrams and Nancy Grace arguing about old cases and cable news obsessions, is airing its season finale tonight. To be completely honest, I don’t remember its season premiere. That would not have happened when there were only 200 channels!
For the record, their final “conversation” revolves around the murder of Laci Peterson and the sketchy behavior of her husband, Scott.
In other season finales, Riggs and Murtaugh find their personal dynamic changed by Murtaugh’s increased responsibilities on “Lethal Weapon” (8 p.m., Fox, TV-14).
Also wrapping up its second season, “Bull” (9 p.m., CBS, TV-14) and crew try to present new evidence in a murder trial, even after a verdict has been reached.
— There was a time when most sitcoms avoided storylines about rich people. Viewers preferred Gilligan and the Skipper to the Howells. Even a 21st-century series like “Riverdale” has us pulling for Archie, Jughead and Betty over the snooty Lodges.
But on cable, the rules are reversed and seemingly wealthy people vie to get on reality series that are little more than “unscripted” sitcoms.
USA gives us the sixth season of “Chrisley Knows Best” (10 p.m., TV-14), about a Georgia family with more money than sense. Also on USA, “The Cromarties” (10:30 p.m., TV-14) documents the antics of Antonio Cromartie, a former NFL cornerback and the blended family of six he shares with his wife, Terricka.
— It’s not every day that a sci-fi series and an art miniseries share a subject. Much like last week’s installment of “James Cameron’s Story of Science Fiction,” tonight’s “Civilizations” (8 p.m., PBS, TV-PG, check local listings) dwells on the subject of first contact.
Just as music was the shared “language” in “Close Encounters of the Third Kind,” art has served as a bridge when cultures, once separated by vast oceans, met for the first time. The opening of Japan to trade in the mid-19th century exposed Europeans to drawings, paintings and woodcuts that impacted Western art well into the 20th.
Not every story has been so uplifting. When the Spanish conquistadors encountered Aztec and Incan art in the early 16th century, their appreciation extended to melting it down for its gold and silver.
TV-themed DVDs available today include the U.K. series “Ackley Bridge,” about immigration and assimilation in a Yorkshire town.

CULT CHOICE
— You’re gonna need a bigger summer! Now seen as the granddaddy of the summer blockbuster, the 1975 shocker “Jaws” (8:35 p.m., AMC, TV-14) did not hit theaters until June 20th. This year, “Avengers: Infinity War” is considered a “summer movie,” but was released on April 27.
