Improv actor and comic Stephen Colbert flexes the hosting muscles he honed over nearly 1,500 episodes of the popular and critically celebrated "The Colbert Report" at the helm of this long-running late-night talk show. Following the genre's classic formula, each show kicks off with a monologue and a look at recent headlines, and features sketch comedy, celebrity interviews and musical performances. Joining Colbert is his bandleader, Julliard-trained Jon Batiste, and house band Stay Human. The show is filmed in New York's famed Ed Sullivan Theater, the longtime home of "The Late Show."

Emmy-winning funnyman Jimmy Kimmel serves up comedy bits and welcomes guests that include other comics, celebrities, athletes and musicians, as well as everyday people with unusual or compelling personal stories. Kimmel's family and friends take part in the festivities, including his Cousin Sal, Uncle Frank (until his death in 2011) and childhood friend Cleto Escobedo III, who leads the show's house band. Recurring segments include the FCC-pleasing This Week in Unnecessary Censorship in which they take TV clips and "bleep and blur things whether they need it or not," as Kimmel describes it. But it's too bad they consistently run out of time for Matt Damon's segment.

With his signature monologue and sharp newsy segments like "A Closer Look," Seth Meyers hilariously breaks down the day's biggest stories and takes the current political circus head-on. He then welcomes Hollywood's most beloved A-list guests, as well as people not seen anywhere else in late night, like political figures and other interesting newsmakers. With fan-favorite comedy segments that become viral sensations, and the talented 8G band at his side, Seth consistently brings home the last laugh.

Live from New York for more than four decades, celebrity hosts join an award-winning ensemble cast to perform comedic sketches, satirical news and digital shorts, alongside popular musical acts. Capturing the pop-culture zeitgeist, the show's sketches and segments often go viral the next day. Over the years, cast members have included Jimmy Fallon, Will Ferrell, Tina Fey, Kate McKinnon, Seth Meyers, Eddie Murphy, Bill Murray, Mike Myers, Amy Poehler, Chris Rock, Maya Rudolph, Andy Samberg, Kristen Wiig, and many more, as well as recurring guests such as Alec Baldwin, Melissa McCarthy and Steve Martin. From executive producer Lorne Michaels, "SNL" is widely considered an American late-night institution and continues to earn critical praise.

Heeeere's Conan! The former longtime host of "Late Night" and abbreviated presenter of "The Tonight Show" moves his talk show act to the cable arena, where he becomes the staple of TBS' late-night talk show lineup. Making the transition to basic cable with Conan is his on-again, off-again sidekick/announcer, Andy Richter. Said O'Brien in his typical dry tone, "In three months I've gone from network television to Twitter to performing live in theaters, and now I'm headed to basic cable. My plan is working perfectly."

The comic, actress, social media sensation, producer and author of "How to Be a Bawse: A Guide to Conquering Life," Lilly Singh brings her unique perspective to late night as she hosts celebrity interviews, talks current events, performs musical and sketch comedy, plays games, and more. A self-proclaimed unicorn, the multi-faceted star's debut in the late-night landscape is especially noteworthy as she's a Canadian woman of Indian descent, combining a fresh take on the day's events, pop culture, diversity and life.
