GreatWarThe Centennial of the start of World War I actually occurred two years ago in Europe. America didn’t get involved until two years in; and so our 100th anniversary events are a couple of years later as well. The big, six-hour, three part “The Great War” (PBS, 9 p.m.) produced for “American Experience” concentrates largely on that experience; how the states did its best to look another way as Europe was being divided by advancing Germans.

The first third goes until war was declared in 1917, following an election the year earlier in which Woodrow Wilson was narrowly re-elected in part on the phrase “He kept us out of war.” The wide ranging history also takes a look at the burgeoning peace and pacifist movements, largely led by women. It continues Tuesday and Wednesday.

One of the great series of the decade (and certainly the best spin-off), “Better Call Saul” (AMC, 10 p.m.) returns for its third season, with the two brothers Bob Odenkirk and Michael McKean still trying to get along. Catch all of season two in a marathon that begins this morning at 11:20 a.m.

The outwardly spoofy “Angie Tribeca” (TBS, 10:30 p.m.) is back for its third goofy season as well.

An autistic Muppet joins “Sesame Street” (PBS, 7 a.m., check local listings; HBO, 8 a.m.) just as network funding is threatened.

Yelp isn’t always the most reliable guide to businesses and services; too many of its negative reviews are written by impatient customers who while waiting for their server. Nonetheless, on the new “Help My Yelp” (Food, 10 p..m.), Monti Carlo helps restaurant rise above their bad online reviews.

Don Rickles, who died Thursday at 90, is featured in three episodes of “The Friars Club Roasts” (GetTV, 10 p.m.).

“Pawn Stars” (History, 10 p.m.) is back for its 13th season.

“Friday Night Tykes: Steel Country” (USA, 11 p.m.) is back for a second season but on a new network.

Charo is already gone from “Dancing with the Stars” (ABC, 8 p.m.) after the second week? So is much of the entertainment. Next to go tonight? Very likely Mr. T.

Knockout rounds continue on “The Voice” (NBC, 8 p.m.).

It’s Bell Biv Devoe vs. SWV on “Hop Hop Squares” (VH1, 9:30 p.m.).

Franco paints a mural on the wall outside “Superior Donuts” (CBS, 9 p.m.).

It’s only part two of a three hour reunion on “Vanderpump Rules” (Bravo, 8 p.m.).

“Nancy O’Dell Remembers” (Reelz, 9 p.m.) — not furniture shopping with a leering lout and the future President — but her recollection of Joan Rivers, in this episode.

Harry Connick Jr. guest stars as a new pal on “Kevin Can Wait” (CBS, 8 p.m.).

A rescue is attempted on “Taken” (NBC, 10 p.m.).

Robert Osborne didn’t just leave a will, he left his picks for movies in April on Turner Classic Movies. His choices: “Tales of Manhattan” (8 p.m.), “O. Henry’s Full House” (10:15 p.m.), “The Seventh Veil” (12:30 a.m.), “The Story of Three Loves” (2:15 a.m.) and “Dead of Night” (4:30 a.m.).

NBA action includes Washington at Detroit (TNT, 8 p.m.) and Houston at Clippers (TNT, 10:30 p.m.).

In college baseball, it’s Duke at Miami (ESPNU, 7 p.m.).
