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."

An extension of Bravo's "Watch What Happens" reunion specials and the original live online shows, this interactive series -- live on the East Coast -- is hosted by former Bravo programming executive Andy Cohen, who welcomes guests from some of the cable network's most popular series, as well as other entertainment stars, to chat about pop culture and celebrities in the news. In 2017, the show took on a new title -- "Watch What Happens Live With Andy Cohen" -- as part of an overhaul that included a remodeled studio offering a designated performance space for musical guests, a staple of most late-night shows.

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.

Hailing from Rockefeller Center in the heart of New York City, Jimmy has made it his mission to make sure viewers end the day with a smile. Each weeknight, he hosts A-list guests, from movie stars to athletes, comedians, public figures and everyone in between. He also delivers a signature nightly monologue, performs in topical comedy sketches, plays fan-favorite games, and presents recurring segments like Thank You Notes. Today's popular musical guests also stop by to perform alongside house band The Roots.

Smart-alecky, ribald and whimsical, this series rose to become a critical darling and dorm favorite after a rocky start in 1993. Originating from New York's legendary Rockefeller Center, the show features a house band led by longtime drummer of the E Street Band, Max Weinberg. Recurring characters include Triumph the Insult Comic Dog.

Veteran TV personality Carson Daly (also known for "Total Request Live," "Today," "The Voice" and the annual special, "New Year's Eve with Carson Daly") is the host of this unique talk show that includes interviews with actors, comics, filmmakers as well as a variety of other artists. Also featured in the program are musical performances filmed at locations throughout Los Angeles and in other cities. By filming on location, the show allows viewers to experience each guest in an intimate and unique setting.

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."
