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.

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.

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.

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 that began a year earlier with the premiere of "Lopez Tonight." 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."

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.

These days, sometimes it's harder than ever to tell what's haute and what's naute -- erm, not. To make sure you're on top of it all, Giuliana Rancic and her team (which consists of Melissa RIvers and Brad Goreski) dissect the celebrity fashion blunders and triumphs of the moment.

Broadway, television and film star James Corden takes over the reins of the late-late-night franchise at CBS from fellow U.K. import Craig Ferguson. The British performer -- whose previous hosting gigs include five years of The Brit Awards -- puts his charm, warmth and creative instincts to use as he interviews celebrities and newsmakers, and hosts musical performances in his post-"Late Show" time slot.
