1) “Sesame Street: 50 Years of Sunny Days,” 8-10 p.m. today, ABC. The week starts and ends with eternal concepts. First, “Sesame” (shown here), which began 51-and-a-half years ago. It soared via TV savvy – clever songs, fun graphics, crisp editing and (especially) Muppets. But this special will focus strongly on the serious side – from a 1992 attempt (which was scrapped) to address divorce to the current look at racial justice. Guests include Anthony Fauci, Jill Biden, Stevie Wonder, Whoopi Goldberg and more.
2) “The Story of Latenight,” 9 p.m. and midnight ET Sunday, CNN. Now the other endless concept: TV used to go blank by midnight. Then NBC’s Pat Weaver (Sigourney’s dad) launched “Tonight” in 1952. He thought it would have news and sports; Steve Allen, its host, preferred comedy, music and talk. The result, one person says, was “chaotic” and “joyous.” When Allen went to prime time, NBC stumbled for a while, then discovered Jack Paar and Johnny Carson … which is where this fun opener ends.
3) “Frontline: The Virus that Shook the World,” 9-11 p.m today and 10-11 p.m. Tuesday, PBS. We meet a food-blogger, young and cheery. A newlywed when her town (Wuhan) went into lockdown, she made videos in an empty cityscape. We also see the unequal impact of a shutdown: A Russian ballet star retreated to a country home; a Brooklyn woman was wedged into an apartment with four kids. And we hear the blogger’s question: Why didn’t we learn from Wuhan and simply have a full-scale shutdown?
4) “Mayans M.C.,” 10 p.m. Tuesday, FX, rerunning at 11. His brother warned him that you can’t be in two worlds, but EZ keeps truing. After a brutal (and deadly) battle with other bikers, he went to a warm family dinner with his sweet girlfriend Gaby. Now the double life implodes, in an hour that is violent and disturbing, but beautifully crafted. It’s often quite mellow, but then has two fierce scenes – Galindo with his wife (whom he suspects of plotting against him) and then EZ and Gaby, in a stroll downtown.
5) Presidential speech and alternatives, 9 p.m. ET. There’s no official State of the Union speech in the first year, but most presidents do a variation. Two days shy of the 100-day mark, Joe Biden has his turn. Big networks will cover it (and, in the West, give part of prime time back to the stations). Alternatives include an intense “Nancy Drew” rerun (9 p.m., CW) and movies: “Casino,” 7 p.m., Paramount; “Bourne Identity,” 8 p.m., AMC; Julia Roberts’ “Wonder,” 8:30, Freeform; and “61*,” 9 p.m., HBO.
6) “Let’s Be Real” debut, 9:30 p.m. Thursday, Fox. “The Moodys” – a clever show that never found an audience – has been pulled. Instead, Fox has four episodes of this show from Robert Smigel (creator of “TV Funhouse” and Triumph the Insult Comedy Dog), mixing puppets and people. Its election special last fall ranged from sharp wit to moments that only Triumph would enjoy. Now those puppets (Biden, Trump, etc.) meet new ones for Andrew Cuomo, Ted Cruz, Anthony Fauci, LeBron James and more.
7) “MacGyver” series finale, 8 p.m. Friday, CBS. The other Friday CBS shows have each seen their ratings drop 15 percent, but are still doing well; they’ll be back next season – the fourth for “Magnum P.I.” (9 p.m.) and 12th for “Blue Bloods” (10). But “MacGyver,” with a 22 percent drop, is ending after five seasons. In its last new episode, Mac and Riley go missing. Waking up in a corn field, with no idea what happened, they must figure out who took them … and how to get nanotrackers out of their bodies.
8) “International Jazz Day 10th Anniversary Celebration,” 9-11 p.m. Friday, PBS. Ever since 2012, there have been worldwide jazz events on April 30, culminating with a mega-concert. Last year, that went virtual; this time, we get highlights from the first eight years. Some of the instrumental solos may tax the patience of casual fans, but there are vibrant moments from Annie Lennox, Stevie Wonder, Sting, Aretha Franklin, Wynton Marsalis, Dianne Reeves and more, plus a potent “Imagine” finale.
9) “Legends of Tomorrow” season-opener, 8 p.m. Sunday, CW. As last season ended (11 months ago), the team defeated the Fates and celebrated … until Sara (Cathy Letz), the captain, was kidnapped by the Aliens. Now Rory and Behrad search for someone to help; Constantine (Matt Ryan, who has played the same role in two “Constantine” series) tries his magic. We also see Sara trying to escape, even releasing some Aliens into the timeline. Then she’s shocked to learn the identity of one of the captors.
10) “Pose” season-opener, 10 and 11 p.m. Sunday, FX; reruns at midnight. “The world is cold and cruel and full of disease,” Pray Tell rages. That seems current, but this is 1994. AIDS has taken many of his friends, another is in critical care and his boyfriend has tested positive. Pray (brilliantly played by Billy Porter, who has two Emmy nominations in the role) crumbles into alcoholism. This two-parter works as a self-contained story, while launching the six-week final season for this harsh but well-made show.
