The first of what will be four specials this month on the death of 6-year-old JonBenet Ramsey in Colorado nearly 20 years ago starts with “The Killing of JonBenet: The Truth Uncovered” (A&E, 9 p.m.) which includes a 1998 interview with JonBenet’s older brother and a more recent interview with her father.
“The Comedy Central Roast of Lowe” (Comedy Central, Spike, TV Land, 10 p.m.) seems needless; what did that guy ever do to deserve this annual trawling into crude insults, now spread on three networks as if it’s a presidential news conference. But the other guests of the event are roasted as well and they include Peyton Manning, Rob Riggle, Ralph Macchio and Jewel, for some reason. David Spade is host and there doesn’t seem any reason Ann Coulter should be there, except that her hero Donald Trump was roasted (in an event he encouraged) a few years back.
Product placement turns to corporate history in the three-night miniseries “Harley and the Davidsons” (Discovery, 9 p.m.), which goes to the early days of the motorcycle company, starring Michiel Huisman, who plays young Ned Stark on “Game of Thrones.”
Pot peddling is the new comedy premise this fall. Before HBO’s “High Maintenance,” Here’s “Mary + Jane” (MTV, 10 p.m.) about two young women who try their hand at marijuana delivery. Is it a surprise that Snoop Dogg produces?
It comes alongside another new comedy, “Loosely Exactly Nicole” (MTV, 10:30 p.m.) about the life of the exuberant personality Nicole Byer.
Wrapping up its series, meanwhile, the one hour “Hit the Floor: ’Til Death Do Us Part” (VH1, 9 p.m.) provides an answer to its cliffhanger about who shot Jelena, and includes a marriage.
Another finale to note is the last episode ever of “Rizzoli & Isles” (TNT, 9 p.m.), the network’s most popular series after seven seasons, as Angie Harmon’s character moves to Washington for a job.
In the importune new Australian series “800 Words” (Acorn, streaming), a widowed newspaper columnist moves his teenage kids to an isolated seaside town.
Too early to start marking the impending anniversary? “15 Septembers Later” (History, 9 p.m.) looks back at 9/11 with interviews with George. W. Bush, Dick Cheney and Rudy Giuliani.
Actual reporting (rather than pundit panels) returns to CNN with the debut of two two-hour profiles of the Presidential candidates, “Essential Clinton” (CNN, 8 p.m.) and “Essential Trump” (CNN, 10 p.m.). Then they’ll probably assemble a panel to discuss them.
Summer is almost over on “Bachelor in Paradise” (ABC, 8 p.m.). The finale is Tuesday.
And the top four dance on “So You Think You Can Dance” (Fox, 8 p.m.).
One Labor Day offering looks at the intense work involved in making sake in Erik Shirai’s documentary “The Birth of Sake” tonight on “POV” (PBS, 10 p.m., check local listings), which follows the process of the Yoshida Brewery.
The national finals of “American Ninja Warrior” (NBC, 8 p.m.) continues.
Baseball today includes Cubs at Milwaukee (ESPN, 1 p.m.), St. Louis at Pittsburgh (ESPN, 4 p.m.) and Arizona at Dodgers (MLB, 8 p.m.).
College football has one game: Mississippi at Florida State (ESPN, 8 p.m.).
Final rounds are played in golf’s Deutsche Bank Championship (Golf, 11 a.m.; NBC, 1:30 p.m.).
And the men’s and women’s round of 16 continues at the U.S. Open (ESPN2, 11 a.m., 7 p.m.).
This year is the 100th anniversary of D.W. Griffith’s classic “Intolerance” (TCM, 8 p.m.). But it is also the 75th anniversary of “Citizen Kane” (TCM, 11:30 p.m.), the 80th anniversary of “My Man Godfrey” (TCM, 1:45 a.m.) and the 60th anniversary of “The Searchers” (TCM, 3:30 p.m.).
